Hi All,
I am using Lucene for creating indexes. There is one field as email which
stored the email id.
I have few queries regarding searching:
1. I want to search for all the records having domain as gmail.com . So,
is there a way by which I can do a partial search on email field such that
I get
One way of doing it is while parsing email if it has .gmail.com add it to
different field also.
Warm Regards,

Usually if you negate the keyword then that document will be skipped. So what
else you want to search. Design of fields is very important.

Thanks a lot Daniel, I will try this option. :)
Is there a way to search for not equal to query alone?

Hi Aditi,
You can search using NOT operator. You can go through below link for Query
details http://lucene.apache.org/java/docs/queryparsersyntax.html

Thank you Allahbaksh for taking so much pains. The link says it cannot be
used alone.
Note: The NOT operator cannot be used with just one term. For example, the
following search will return no results:
NOT jakarta apache
Thanks,
Aditi

Hi Aditi,
As Rohit said, the best way to solve this problem is to have two fields for
indexing an email-id, one for the username and another for domain name.
Having two fields and using a Boolean Query with MUST condition should solve
your problem. You can also perform restricted search with the

Hi Sebastin ,
Why dont you index all data into single or some fixed number of indexes and
search over them. You can always restrict your search using the range query
based on user given inputs.

Thanks for your reply, Mark.
This was my original code for constructing my query using FuzzyQuery:
BooleanQuery query = new BooleanQuery();
if (artist.length() 0) {
FuzzyQuery artist_query = new FuzzyQuery(new Term(artist,
artist));
query.add(artist_query, BooleanClause.Occur.MUST);
}
Hi,
I have around 10 different indexfiles to request. Is it better to do
this via one request to one MultiReader or is better to request the 10
indeces one after another?
Especially for doing some filtering on the result with a HitCollector
it might by easier to use the multi request
Could you tell me what's wrong here, please?
There are potentially a number of factors at play here.
Your use of FuzzyLikeThis is fine - just tried the code on my single-term
Paul query and as I outlined before it is doing a much better job of matching
(Paul~= results Paul,Paul,PaulPhul
Thanks! Lucene in Action is very helpful.

I'm sorry, the problem was with the way the id was being indexed. It was
marked as tokenized, so I when searched for it's untokenized form I was not

Basically I think you need to use NGramFilter, this will be alot faster
than the searches you list, but will make your index much larger too.
In Solr this can be achieved with something like:

Or subclass QueryParser and override the getBooleanQuery() method to do this
behind the scenes using MatchAllDocsQuery.
