Document search app is a full-text search within the textual content of documents. The full-text search is a two-stage process: Full-text indexing of documents and text lookup in the created index.
At the stage of indexing, text from documents is extracted and added to the index – an optimized structure containing information about in which documents and at what positions each word occurs.
At the search stage, the index allows you to very quickly find documents containing words from the query.
Further special algorithms determine which documents contain the entire phrase you are looking for.
This web application is built using search engine implemented in the GroupDocs.Search for .NET library and has the following features:
-
Three search modes: a whole phrase, all words from a query, any word from a query.
-
Case sensitive and case insensitive search.
-
Fuzzy search (approximate string matching).
-
Search for various word forms, as well as synonyms and homophones.
-
Correction of the keyboard layout for entering a query.
-

-
Support for OCR on images – separate and embedded in documents.
-
Documents can be uploaded from a local PC or from a global network.
Search results can be presented:
-
In the form of a list of phrases containing query words.
-

-
As a page-by-page formatted document with highlighting of found words and phrases.
