Hi,
i have two applications on an windows machine. One is the searchengine where
the index is can be searched.
The second application runs one time on a day which updates
(deletions/adding)
the index.
My question:
The index is already opened (Indexreader) by the frist application. Is there

FieldCache was designed with searching in mind, where there can only be a
single indexed Term for each doc (otherwise how would you sort a doc that

Hi,

DotLucene is the old name, Lucene.Net is the official name. You can find

Hi, Xin, in my understanding , the document in Lucene is a term of
collection of fields, while a field is pair of keyword and value, tough it
can be indexed or stored or both. That is plain structure. if you wanna
index a deep tree structure such as complex objects and keep those

Hello-
I am just wondering if any one has encountered any good strategies for
sharing search records between a Linux based server using Lucene and a
Windows based client using DotLucene.
I am doing all the indexing on the server ( i.e. the master index is
contained on the server) and I would lik

Hi, Rupinder,
Our algorithm is a little different from what PubMed does. We have scoring
for each mesh term, which will affect the search result.
What do you think the difference would be for these two:
document.addField(Field.Keyword("mesh", ""));
and
document.addField( new Field( "mesh", "
Hi Xin
then perhaps you can change it to Field.Index.TOKENIZED, but i was
not aware that pubmed boosts mesh terms, they broadly classify terms as
major and minor, if you plan to use this simple system of classification
consider adding the major terms twice to the document ?

Hi, Rupinder,
My understanding is Field.Index.NO_NORMS disables index-time boosting and
field length normalization at the same time. But I do need index-time
boosting to store the scoring of each mesh term. Have I missed anything?
Thank you very much for your help,
Xin

hi Xin
this is take a look at this you can add multiple fields with the name

for ( i=0; i< meshList.size() ; i++ ){
meshTerm = meshList.get(i)
document.addField( new Field( "mesh", meshTerm.semanticWebConceptId,
Field.Store.YES , Field.Index.NO_NORMS );
}

Not sure of the solution though. But FieldCache.DEFAULT.getStrings()
is returning a String[], with one String for each document. Seems your
field is analyzed into multiple String values.

Performance wise, Lucene search is much faster for full-text search.
If you only do "Employee ID" search, or exact match of Names,
database's search can do a good job already.
If it's regarding the index maintenance, you should have a updated_at
column for each record, and select the latest recor

Thank you for your reply. I had thought about the first two solutions
before. If we apply one doc for each MeSH term, it would be 26 docs for each

any problem if there are too many documents? If we apply field name

We are upgrading from Lucene 1.4.3 to 1.9.1, and have many customers
with large existing index files. In our testing we have reused large
indexes created in 1.4.3 in 1.9.1 without incident. We have looked
through the changelog and the code and can't see any reason there should
be any problems
Not sure if it helps, but I have been using Luke (webstart version) from
it's website for quite sometime now for inspecting and manipulating my
indexes built using Lucene 2.0. I may not be a power user of Luke in that
sense, but I haven't found any issues using the basic features.

Hi Andrzej,
a month ago you mentioned a new Lucene 2.0 compatible Version of luke.
Does it exist somewhere?
Thanks
