Sorry, but I don't know what exactly you mean by compile from these locations.
Do you mean I could download and customize the code?

Thank you, Tim.
I have read that ComplexPhraseQueryParser has issues while searching in more
than one field. In my case, I need to search the value in multiple fields of
each document.
Do you think it is possible? Also, could you please direct me to any useful
links for ComplexPhraseQueryParse
Hi,
Can Lucene support wildcard searches such as the ones shown below?

I have used StandardAnalyzer in my code and it is working fine. One of the

In my current implementation of Lucene 4.3 where there are millions of indexed

As part of this, I store all the results in the session and then let the user

Hi,
I am using the regular QueryParser to form a PhraseQuery. It works fine, but
when it consists of a hyphen, it gets removed, hence resulting in unexpected
results.
Note: I am NOT using the QueryParser.escape() method before parse() method as
it results in a BooleanQuery, while I want a Phra
Hi,
I found a solution to my earlier question. If I provide search strings in
lowercase characters, then it works fine. For eg. if I submit N(abc,corp)
instead of N(ABC,CORP) as my search string then it works fine! Although my
index strings are all in upper case letters.

Ian,
Thank you very much for your valuable inputs.
The surround parser sounds very powerful and it just may be the single answer
to all what I am looking for. I have been trying hard to find an example for
its implementation but haven't been able to find one online. Could you please
