Advanced Search

Browse allows you to go through a list of items in some specified order:

Browse by Community/Collection takes you through the communities in alphabetical order and allows you to see the subcommunities and collections within each community.

Browse by Title allows you to move through an alphabetical list of all titles of items in ETD@IISc.

Browse by Author allows you to move through an alphabetical list of all authors of items in ETD@IISc.

Browse by Date allows you to move through a list of all items in ETD@IISc in reverse chronological order.

You may sign on to the system if you:

• wish to subscribe to a collection and receive e-mail updates when new items are added
• wish to go to the "Thesis Submit" page that tracks your subscriptions and other interactions with ETD@IISc requiring authorization (if you are a submitter for a collection, for instance.)
• wish to edit your profile

Submit is the ETD@IISc function that enables users to add an item to ETD@IISc. The process of submission includes filling out information about the item on a metadata form and uploading the file(s) comprising the digital item. Each community sets its own submission policy.

Submit Thesis is a personal page that is maintained for each member. This page can contain a list of items that are in the submission process for a particular member, or a task list of items that need attention such as editing, reviewing, or checking. In the future this page will also maintain information about personal services offered by ETD@IISc, such as e-mail notification when new items are added to a collection.

Edit Profile allows you to change your password.

About takes you to information about the DSpace project and its development.

To search all of ETD@IISc, use the yellow search box at the top of the navigation bar on the left (or the search box in the middle of the home page)

To limit your search to a specific community or collection, navigate to that community or collection and use the search bar on that page.

ETD@IISc uses the Jakarta Lucene search engine. Here are some search hints:

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

If your site is enabled for full-text searching, the text you entered will also be searched against the full text of all archived documents. For more information on full-text searching please contact your ETD@IISc Administrator.

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"

Truncation
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.

Stemming
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

  or  

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".

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 ETD@IISc, 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.
