Hi Li Li
If you want to support some query types and not others you should
overide/extend the queryparser so that you throw an exception / makes
a different query type instead.
Similarity doesn't do the actual scoring, it's used by the Query
classes (actually the Scorer implementation used by the

when you are indexing, use termvectors
org.apache.lucene.document.Field.TermVector
set this in the Field object constructor when you create your Field objects
at index time.
i've never done it but i'm pretty sure these can be retrieved at
search time using one of the

Hi,
if you want to store word+value pairs then use lucene scoring to weight
the words with higher vaules against them, you should look at using payloads
and the DelimitedPayloadTokenFilter which lets you specify e.g.
word1|value1 word2|value2 ...
and the values are stored as payloads against the w

Use solr-user@ instead of java-user@ . You'll find more knowledgeable people.

Hello All:
Can any one suggest me the best way to get the no. of occurrences of each
word per document in Lucene?
Eg: Let the indexed text be:
If you are posting a question, please try search first. Your question may

Now if I search for the word 'question', then I w
Thanks for your reply Grant.
I checked out the TokenStream class and you are right but I'm afraid I
didn't really make myself understood. What I want is to be able to create a
Document out of key-value pairs of terms and float numbers representing word
weights, insert the Document in the index and

I want to only support boolean or query(as many search engine do). But
I want to boost document whose terms are closer.
e.g. the query terms are 'apache lucene'

Yes it has :)
Get ready for even more change in that area though :)

Hi,
I have recently been in charge of converting code that was using
pre-3.0 API to be compatible with 3.0 API.
There was a piece of code which was storing a date field:
String date = "20091231131415"; // MMddHHmmss
new Field("creationDate", date, Field.Store.YES, Field.Index.UN_TOKENIZED);
Great, thanks!
I am curious to learn if anyone has used Lucene/Solr as a
document-oriented db - any experiences to share? Lessons learned?
I am considering a similar application using Solr and want to ensure
we have a handle on potential issues.
Thanks,
Shashi
