We have an internal search engine developed on following technologies.
Currently it will index all the PDF files which are located under a particular path and whenever I give a query/string in intranet search webpage, it is pointing me to the files where the requested query is available. but when I search for a long/full sentence of (e.g.: what is the capital city of India) it is unable to find it in the database even if it exists. it is successfully working when I query with a single/double words but not when I search for a full sentence.
I need an upgrade for this tool where as I would like to enhance few more options and little artificial intelligence to faster the query results aswell as export it to a particular application/clipboard.
Please feel free to post your quotation and/or queries and I would be glad to answer...
