Exact Searching

If the query is contained in quotes then the results will contain exactly those results otherwise it may be in some other order. ( Eg:- searching for good boy will show both good boy as well as boy good, but when exact search is selected “good boy” only results of good boy will be shown.

Did You Mean

If a particular word is not found then we try to find best possible matches to the word.

GUI

GTK+ has been used to make User Interface for this application, the key benefit of using this is it adapts to the theme you are using on your desktop

alt text

Ease of use

When a particular file is selected, all occurences of the query are displayed and on click on a particular occurence the file opens from that particular Page Number or Line Number of the file.

Other Features

Stemming of Words (Eg:- Spelling -> spell; heroes -> hero). This feature helps us to ignore the form of verbs
Saving of Indexes:- Once you have indexed a file we save the indexes of it so that we don’t have to wait again for indexing it.
Recent searches are tracked so that next time when you have to search for the same query you can directly do it.
Searches for both PDF as well as txt files.
Ranking is done by TF-IDF algorithm

Data Structures:

The data structures used in the project are Dictionary, Lists and Sets.

Main Index Dictionary = { Word : { Book : { Page/Line : [occurrences] } } }
Individual File Dictionary(The one that is saved) = { Word : { Page/Line : [occurrences] } }
Answer = { Book : [Page/Line Numbers] }
