Hi,
I recently started using Lucene. There are lot of articles and news
about undestanding Lucene at the API levels .
Can anyone help me understanding in depth what happens internally
inside a lucene index how it stores and details about the which
Datastructure lucene uses for inverted index.
Apache Tika:-You can Use to Extract text from PDF,word Documents.
It internally uses Apache POI for Extraction of text from office documents..
It uses PDFBOX for Extraction of text from PDF Documents..

Hi,
Is it mandatory to use "Store.YES" when using Highlighting Feature.
is it Possible to use Highlighting Feature without using "Store.Yes" while

Please Kindly Help.

Hi,
I think using CompressingStoredFieldsFormat Feature introduced in Lucene
4.1 may help reduce index size.
Any other comments and suggestions are welcome in this topic..
