Re: Embedding SOLR in Dot NET Application
Solr is not a library like Lucene. Solr works like Webservice application over http. It works over http so you can easly integrate it in any application. it takes input as http parameters and returns response in different forms like xml, json, php, csv etc.So you can use any response type for your application.You have to parse response and use into your application - Grijesh -- View this message in context: http://lucene.472066.n3.nabble.com/Embedding-SOLR-in-Dot-NET-Application-tp2197589p2197653.html Sent from the Solr - User mailing list archive at Nabble.com.
WARNING: re-index all Lucene trunk indices
If you are using Lucene's trunk (to be 4.0) builds, read on... I just committed LUCENE-2843, which is a hard break on the index file format. If you are living on Lucene's trunk then you have to remove any previously created indices and re-index, after updating. The change cuts over to a more RAM efficient and faster terms index implementation, using FSTs (finite state transducers) to hold the term index data. Mike

What we definitely noticed was a marked improvement in maintaining connections to the database. At that time, our data import handler used to take some 6-7 hours, and we had all kinds of problems with dropped connections while using the Microsoft JDBC driver. Things improved a lot with jtds. Even though the problems did not entirely go away, they were minimised enough that the glitches could equally well be attributed to network issues, or issues with the database server. Regards, Gora

I managed to do that by using TemplateTransformer

Only problem is that delta import fails to perform delete to the

delete so delete by id doesn't work.

I have a dataimporthandler config file as below. It contains multiple

All data are from a database. Problem is item/company and other entity all
have the field 'id', with value start from 1 to n. In this case,
item/company etc. will step into each other.
Is there a way to prevent is from happening. Such as designate different
entity to different partition.
One way I can think of is to seperate different entity to different
instance, which is not ideal solution IMO.
Would some one point me to a reference? And also give some instructions?

Re: Searching similar values for same field results in different results
Often adding debugQuery=on to the URL can show you very useful information that helps pinpoint the problem. I confess I don't see anything amiss in what you've shown though. Also, look at the schema browser page off the admin page, and look at your themes field to see what is actually in your index, it may surprise you.. Finally, the admin/analysis page (turn debug on) may also help you to see exactly what tokenization is happening when indexing and querying. I'd guess that the behavior isn't exactly what you expect.

Re: (FQ) Filter Query Caching Differences with OR and AND?
Thank you Jonathan. fq=foo:barfq=foo:baz seems to be the better alternative for fq=foo:bar AND foo:baz if foo:bar and foo:baz were often used in different combinations (not always together). However, in most of the usecases I can think of, an fq=foo:bar OR foo:baz-behaviour is expected and it would be nice if this fq would benefit from a cached fq=foo:bar. I can imagine why this is not the case, if only one of two fq-clauses were cached. However, when foo:bar and foo:baz were cached seperately, why not benefiting from them when a fq=foo:bar OR foo:baz or fq=foo:bar AND foo:baz is requested? Who is responsible for putting fq's in the filterCache? I think one has to modify the logic of that class do benefit from already cached but recombined filterCaches. This would have a little bit less performance than caching the entire foo:bar AND foo:baz BitVector, since you need to reproduce one for that special use-case, but I think the usage of the cache is far more efficient, if foo:bar and foo:baz occur very frequently but foo:bar AND foo:baz do not. What do you think?

Re: (FQ) Filter Query Caching Differences with OR and AND?
AND/OR/NOT/SUBTRACT combinations for filters would certainly be a useful feature.
