Hi,
As per my knowledge, you may do any of the below processes while searching
(n parallel) just that the changes would not reflect until you reopen the
index readers (by either using the reopen command or closing and opening
them explicitly).
But the downside to this would be, in case your daemon
Hi Steve,
It would be simpler if I have a query called SubPhraseQuery in which case I
do not have to either generate extra terms during ingestion or generate
extra queries during querying. As a user, the best I would hope for is, to
ingest the data from some feed into different fields, run the use
Hi, I have a couple of questions about how to alter the similarity scores.
I need scores that can be thresholded, and whose thresholds remain stable
even when I add documents to the IndexWriter. ie, identity should be a
fixed value such as 1.0. I know that for efficiency reasons, Lucene
doesn't do
Hi,
I'm in the process of trying to optimize searches and avoid the dreaded
OutOfMemoryError s.
We currently return the entire document from each of the search results
and then filter the results using parameters obtained from a database.
Not very efficient.
The idea was to override TopFie

Hi,
Sorry if you get this mail second or third time. Getting mail delivery
errors from gmail for some unknown reason.
This is my last attempt at sending the mail for the day.. :-)
Is there a query in Lucene which matches sub phrases ?
For example if the document text is "new york existing homes
Hi,
Sorry if you get this mail second time. Having some trouble with mail box.
Is there a query in Lucene which matches sub phrases ?
For example if the document text is "new york existing homes *3 bed 2
bath*homes 3 miles from city center 2 rooms" and if user enters
"Brooklyn homes

Can I assume that since nobody replied to this that there's no way to
perform this kind of search? What I think I need is two different
types of conditions:
1) a wildcard conditional that is forced to match against all indexed
values for a field
2) a conditional that matches when NO values at all
Hello *,
I have been trying to find an *efficient *(in terms of performance) way
to get the Cosine Similarity between two Lucene Documents.
I have seen that this can be done with:
1. Converting the document into a query and submitting the query, getting
the results and their score. --TOO
The answer to all 3 is yes, but, you'll have to re-open your
IndexReader to see any of those changes.
An IndexReader always searches the "point in time" snapshot of the
index as of the moment it was opened.
Any & all changes done with an IndexWriter (including opening a new
index in the
Hi,
I am working on extracting information from around 2 to 3 million document
and place it into the memory to retrieve it for filtering search results.
The application will have to extract the information and store it for every
search. I am wondering what will be the best way to store this info
