This will return results from all of the Jane's datasets.

For best results, it's important to choose your keywords wisely. If you're looking for information on Patriot missiles, enter Patriot rather than missiles.

Searching is not case-sensitive, and keywords can be entered in upper, lower or mixed case.

"AND" Searches:
Separate multiple words with spaces to match all of the words.

frigate submarine torpedo = frigate <AND> submarine <AND> torpedo

"OR" Searches:
To match any one or more of the search terms, use the <OR> operator in-between your keywords, for example:

Rocket <OR> Missile

Phrase Searching:
Phrase searching is achieved by entering two or more keywords surrounded by double-quotes. Only exact matches where the keywords appear adjacent in a document will be returned.

An example is as follows:

"mortar bomb"

See 'Advanced Search Help' section for more information on all operators.

Stemming:
The stemming functionality returns documents containing terms that match the root of your term, and stemmed variations. For example:

Destroy> Destroyed, Destroying, Destroys

It's important to note that not all stemmed variations are matched. From the example above, the term Destroyer is not matched.

To return results with no stemming, surround your term(s) with double-quotes.

Ma?ia > Mafia, Maria

hydro* > Hydromechanical, Hydrophones, Hydrographic

*jet > Learjet, Alpha Jet, Water-Jet, Altajet

defen*e > Defensive, Defensible

Boolean Operators:
The Boolean <AND>, <OR>, and <NOT> operators are available for use, and are more powerful than using keywords alone.

The <AND> operator is used to return documents that contain all of your keywords. An example of use is as follows:

destroyer <AND> frigate <AND> phalanx

The <OR> operator is used to return documents that contain any of your keywords. An example of use is as follows:

destroyer <OR> frigate

The <NOT> operator is used to return documents that do not include a keyword. An example of use is as follows:

submarine <NOT> nuclear

In addition, the Jane’s search functionality supports use of the plus and minus characters as alternatives to the <AND> and <NOT> operators, respectively.

An example of their use is as follows:

destroyer +frigate
submarine -nuclear

Note that a space is required between the operator and the preceeding term.

Proximity Operators:
The <NEAR> operator is used to return documents where the keywords are in close proximity to one another. It is more likely that a document will be of greater value to you when your keywords appear close together in a document.

The <NEAR> operator will match documents where your keywords appear within 1024 words of each other. An example of use is as follows:

typhoon <NEAR> RAF

It is good practice to surround all operators with angle brackets as shown, as only the AND, OR and NOT operators can be used without angle brackets.

The <NEAR> operator can be configured to operate with a user-defined range as follows:

<NEAR/N>

This selects documents containing two or more words within N number of words of each other, where N is an integer.

Document scores are calculated based on the relative distance of the specified words when they are separated by N words or less.

For example, if the search expression <NEAR/5> is used to find two words within five words of each other, a document that has the specified words within three words of each other is scored higher than a document that has the specified words within five words of each other.

The N variable can be an integer between 1 and 1,024, where <NEAR/1> searches for two words that are next to each other.
If N is 1,000 or above, you must specify its value without commas, as in <NEAR/1000>.

You can specify multiple search terms using multiple instances of <NEAR/N>, as long as the value of N is the same.

For example, to retrieve relevance-ranked documents that contain stemmed variations of the words lightweight, fighter, prototype, and programme within 10 words of each other, enter the following:

lightweight<NEAR/10> fighter <NEAR/10> prototype <NEAR/10> programme

Phrase Searching:
Phrase searching is achieved by entering two or more keywords surrounded by double-quotes. Only exact matches where the keywords appear adjacent in a document will be returned.

An example is as follows:

"mortar bomb"

Search Precendence:
Your search queries will be read from left to right, but certain operators take precedence over others.

For example, the query below is interpreted to mean: Look for documents that contain Hornet, or look for documents that contain Prowler and Nimitz.

Hornet <OR> Prowler <AND> Nimitz

To change the operator precedence, use parentheses as shown below.

(Hornet <OR> Prowler) <AND> Nimitz

Date Range:
The date range search field allows you to search for documents with a post date between your chosen start and end dates. It’s important to note that this is the date the document was made available for release to our electronic services, and is not the hard copy publication date.

The format for entering dates is DD-MMM-YYYY - (29-AUG-1976), or you can use the calendar buttons to select your dates.

Document Title:
This field allows you to search across only document titles. If a search term is present in a document title, that document is more likely to be relevant to your needs. If you know it, you can also search using a full or part document title, to quickly return just the document you want to view.

Country:
Use the country field, to only return documents related to a specific country. Magazine titles do not support the country field, as the magazine content is often not country specific. Press Ctrl key when clicking on Regions or Countries to select more than one.

# of Results per page:
Allows you to return 10, 20 or 50 results per page.

Company:
The company field allows you to narrow your search, by only returning documents that refer to that specific company. Not all titles make use of the company field.

Score:
The default selection, returns documents ranked according to the search term accuracy within the document. The higher the score, the more relevant the document.

Date (descending):
Returns documents sorted in descending date order, listing the most recent documents first.

Date (ascending):
Returns documents sorted in ascending date order, listing the oldest documents first.

Product (descending):
Returns documents sorted alphabetically in descending publication order, Z-A.

Product (ascending):
Returns documents sorted alphabetically in ascending publication order A-Z.

Dataset Selection:
You are given several options for selecting which Jane's titles you would like to search (e.g. Fighting Ships, Defence Weekly). By default, Janes.com will search all of the available titles (datasets).

The following options allow you to alter the selection of titles to search:

•  Select the specific datasets that you want to search from the list box below.

• The Image Search feature allows you to perform a keyword search across the captions that accompany all images on Janes.com. Search results are returned in the form of image thumbnails, and their captions. Subscribers can then click on a link to see the full image, and the associated publication entry.

• You can sort the search results by score, product or date.

The complete Jane’s content is organized into various groups of related material. Browse uses what is known as category drill-down to allow you to intuitively navigate through your chosen publications.

When you have drilled down to the final category, only documents are displayed.

As you drill down you will notice that what is known as the ‘crumb trail’, will update at the top of the page to reflect the publication and level that you have reached.

For example, if you choose to drill down within the ‘Systems and Equipment’ category, and then the ‘Section’ category within Fighting Ships, the crumb trail will display as shown below.

Should you then wish to drill down into a different title within the ‘Systems and Equipment’ category for example, without clicking on the ‘Back’ button on your browser, you can simply click on the link to "Systems and Equipment" within the crumb trail.

In addition to drilling all the way down to a document, it’s also possible to perform keyword searching at each category level.

There are 5 levels in the browse structure.

• Level 1: The list of datasets (Countries, Images, Markets, News/Analysis, Operational Guides, Organizations, Systems and Equipment)

• Level 2: The list of publications within each dataset

• Level 3: The categories that make up each publication (Company, Country, Date, Section)

• Level 4: The list of companies, countries, dates, and sections

• Level 5: The list of records that match each company, country, date, and section.

It is possible to perform keyword searching using the search functionality, across:

A single dataset at level 1

Single, or multiple publications at level 2

Single or multiple categories at level 3 and 4

Just the list of records in that category at level 5

Being able to drill down into a publication, and then perform keyword searches at that level, gives you more control over what you are searching when compared with keyword searching using the main search page.

For example using the main search page to search across a specific publication section would require you to know the name of that section. Using the browse functionality you can visually select your chosen category, and search across it.
