Error Doc id doesn't match the query in vector searches

Hi, we are currently testing Solr 9.7 and experiencing an error we have not seen before with SolR 9.6.1 and we think the problem might occur in the underlying lucene code basis: ERROR o.a.s.h.RequestHandlerBase Server exception => at org.apache.lucene.search.TopFieldCollector.populateScores(To

hnsw parameters for vector search

Hi, the hnsw documentation for the Lucene HnswGraph and the SolR vector search is not very verbose, especially in regards to the parameters hnswMaxConn and hnswBeamWidth. I find it hard to come up with sensible values for these parameters by reading the paper from 2018. Does anyone have experie

Some questions about StandardTokenizer and UNICODE Regular Expressions

Hi guys Currenly, I'm looking into the rules of StandardTokenizer, but met some probleam. As the docs says, StandardTokenizer implements the Word Break rules from the Unicode Text Segmentation algorithm, as specified in Unicode Standard Annex #29. Also it is generated by JFlex, a lexer/sc

some doubts about nodeblock in *.tim

Dear all , Currently, I'm studying the format of *.tip and *.tim. I found that, in the *.tim it not only stores suffixes information, but it also stores information of the current prefix's child nodes' position.Taks terms 'ab1,abc1,abc2‘ for example, for the prefix 'ab', *.tim stores the suffi

I used to say "when i did some copy operation on the machine the speed may become normal.", it seems not correct. But when forceMerge hangs on IO, if i use the command "echo 3 > /proc/sys/vm/drop_caches", the io become normal again. At 2015-08-21 11:59:30, "dr&quo

Hi ,all Currenty i met a probleam with forceMerge(1). During forceMerging some of my machine spent too much time(10-20 hours for a index size of 15GB). By using some command like top, iostat, jstack. I found that the avg of cpu, and disk is too low, nearly zero. And the size of the the inde

Re: Indexing TREC GOV2 data in Lucene

Hi, I am not sure if there's something in the contrib for GOV2 but it really depends on what you want to parse. If you are just interested in full-text search then it should be similar to parsing a regular document while being conscious of the trec-specific delimiters. It's something like . Howeve

Table Defn and/or ER Diagram of Segment files

Is there an entity-relationship of the segment files and/or Berkeley DB tables (with table definitions)? I'm trying understand the segment files of Lucene and know that a Berkeley DB can be used to store the directory but can't locate any ER diagram or table definitions for the DB. Thanks Ray --

How to make mutually exclusive lists of results

Hi, I currently am using Lucene to index documents. I index 4 fields, the body of the document, the city it is related to, the state it is related to, and the country it is related to. I have a java web application where the user types in some search text.. and it searches the body of the docume
