Hi All,
I found a interesting point mentioned in
http://www.cs.cmu.edu/~shashank/htmlfiles/hacks/lucene.html by Shashank.
Of course there is no doubt that search in Lucene index is faster but
sometimes the retrieving the hitDocs is slower(for Ex. when we try to
retrieve more than 10000 documents from hits). May be my scenario is a
special case but I find the option mentioned in the article can be
optional functionality in future release of lucene.
Small example based on the my integration of lucene in the project ..
I have integrated lucene search engine for one of our project in the
company, there I have a book index with each document has more than 15
fields to do speific search, but out of that after I do the search I
just want to retrieve the value of one field named "DBID" which is the
database table column id and for rendering in the frontend I retrieve
the data from database. In this case I really don't require all the
field values form the document. Also sometimes I get a OutOfMemorry
Error when I try to retriev more than 10000 documents at once.
The advantage I found after I try to implement the above idea, the
performance improved a lot and also I don't get any OutOfMemory error.
Just a small idea which is not entirely mine but I feel its a good option.
With Regards,
supriya
