Search Box

JAIST Repository uses the Jakarta Lucene search engine. Here are some search hints:

What is searched in the general keyword search
The word(s) you enter in the search box will be searched against the title, author, subject abstract, series, full-text and identifier fields of each item's record.

What is not searched - Stop Words
The search engine ignores certain words that occur frequently in English, but do not add value to the search. These are:

"a", "and" , "are" , "as" , "at" , "be" , "but" , "by" , "for" , "if" , "in" , "into",

"is" ,"it" ,"no" , "not" , "of" , "on" , "or" , "such", "the" , "to" , "was"

Use an asterisk (*) after a word stem to get all hits having words starting with that root, for example:

   will retrieve selects, selector, selectman, selecting.

The search engine automatically expands words with common endings to include plurals, past tenses ...etc.

Phrase Searching
To search using multiple words as a phrase, put quotation marks (") around the phrase.

Exact word match
Put a plus (+) sign before a word if it MUST appear in the search result. For instance, in the following search the word "training" is optional, but the word "dog" must be in the result.

Eliminate items with unwanted words
Put a minus (-) sign before a word if it should not appear in the search results. Alternatively, you can use NOT. This can limit your search to eliminate unwanted hits. For instance, in the search


you will get items containing the word "training", except those that also contain the word "cat".

Boolean searching

The following Boolean operators can be used to combine terms. Note that they must be CAPITALIZED !

AND - to limit searches to find items containing all words or phrases combined with this operator, e.g.

will retrieve all items that contain BOTH the words "cats" and "dogs".
You can use space (" " blank) instead of using AND.

OR - to enlarge searches to find items containing any of the words or phrases surrounding this operator

will retrieve all items that contain EITHER the words "cats" or "dogs".

NOT - to exclude items containing the word following this operator, e.g.

will retrieve all items that contain the word "training" EXCEPT those also containing the word "cat".

Parentheses can be used in the search query to group search terms into sets, and operators can then be applied to the whole set, e.g.


The advanced search page allows you to specify the fields you wish to search, and to combine these searches with the Boolean "and", "or" or "not".

You can restrict your search to a community by clicking on the arrow to the right of the top box. If you want your search to encompass all of JAIST Repository, leave that box in the default position.

Then select the field to search in the left hand column and enter the word or phrase you are searching in the right hand column. You can select the Boolean operator to combine searches by clicking on the arrow to the right of the "AND" box.

Note: You must use the input boxes in order. If you leave the first one blank your search will not work.

HANDLES top Japanese

When your item becomes a part of the JAIST repository it is assigned a persistent URL. This means that, unlike most URLs, this identifier will not have to be changed when the system migrates to new hardware, or when changes are made to the system. JAIST Repository is committed to maintaining the integrity of this identifier so that you can safely use it to refer to your item when citing it in publications or other communications. Our persistent urls are registered with the Handle System, a comprehensive system for assigning, managing, and resolving persistent identifiers, known as "handles," for digital objects and other resources on the Internet. The Handle System is administered by the Corporation for National Research Initiatives (CNRI), which undertakes, fosters, and promotes research in the public interest.
