can i remove commit.lock while sreaching in my application

hi all

I am using lucene in my web application.
I am using 2 index directories.  For the first time I will create index in 
index1 directory and next time I will create in index2. I will use flip-flop 
mechanism in two directories.
After creating index all the users who are searching will point to new index 
directory(this I will handle using flags).

So I won’t have searching and adding/deleting documents simultaneously to 
one index directory.

Now can I remove commit.lock file when I am search documents.
As I have a problem like in peak traffic searching is timing out in 
obtaining  commit.lock this is rare but I have to eliminate.

As I understood commit.lock is there not to write anything into index 
directory when someone is search, am I right?
Please let me know if it is wrong assumption

So I am thinking of remove commit.lock when searching for document as multi 
read is allowed on any operating system
If not please suggest me alternative

I am creating IndexSearch object whenever there is a request for searching. 
I will be creating index everyday after adding and removing file to source 
directory where my file reside.

Please give ur suggestion, alternative

Thanking you
mahesh

Lucene doesn't keep any of its locks for longer than it has to.
Therefore, whenever you choose to forcefully remove a lock while Lucene
is running, you are very likely to be making a bad decision.

Please use lucene-user list, don't email directly nor spam the list,
and always try to keep this in mind:
