Probably, Last doubt:
The data in my application is coming from a stream after performing some
functionality.
This stream is getting continously written in the file.
So , effectively, if I open a lucene index and create indexes using this
file, I would be able to create the indexes ..??? Won't I get any kind
of exception from the file as I am still writing data in that file. ???
Guidance is highly appreciated...

If I've understood your question correctly, the answer is yes.
Assuming the input data is coming from another file the flow will be
along the lines of
. Open input file for reading
. Open output file for writing
. Open (or create) lucene index
. For each input record
- write to output file
- add to lucene
Then at the end close the files and the index and you're done.

My most important question still remains.

Indexes. Once indexes are created, I can then perform operation on the

Is it possible to create indexes of a file, data in which is still getting
written...
Any guidance will be highly appreciated.

You'll have to periodically re-index that document, if it's content is
constantly changing.
Alternatively, it's possible to index sub-documents so that each new
"chunk" of content added because a new document, and then you join or
group the results back into a single document ...

using
lucene will help me or not.

If yes, what about the incremental changes which happen in file. Those
details wont be captured in the indexes. Does this effectively means
everytime I try to perform a search I will first create index and then
perform search operation.
Any guidance on this will be highly appreciated. Javadoc does not seem to
provide relevant information on this. Lucene version is 4.4.0
