The reason: GET when passing parameters to the long solr parameters caused. A method, solrServer example is org.apache.solr.client.solrj.impl.HttpSolrServer
// execute the query QueryResponse response = solrServer.query (solrQuery);
Solution: POST instead submit
SolrServer solrServer = new HttpSolrServer("xx"); SolrQuery solrQuery = new SolrQuery(); solrServer.query(solrQuery, METHOD.POST);
2. Conditions for splicing too much, resulting in too many boolean clauses
Solution: Modify solr configuration
profile location: SOLRHOME / CORE_NAME / conf / solrconfig.xml
Find the following configuration:
<maxBooleanClauses>1024</maxBooleanClauses>
1024 changed to 10240
Which, SOLRHOME solr your home directory, CORENAME the name of your core
3. solr index increase did not take effect immediately after
Possible reason: While calling server.add (doc) code, but no commit, it does not update the index immediately solr
The solution: increase after the completion of the index, a commit. Do not add to commit a time, so consumption of performance, it is best to complete a one-time after batch add commit.
solrServer.commit();
This submission submission called hard (hard commit), the use of this document will be submitted immediately persisted to disk, and allows you to query it immediately, because it will open a new searcher, but it is obvious shortcomings, is a waste of performance, and will be submitted to clog the task is completed, using it is very expensive operation. See solrj source discovery implementation commit () method is commit (true, true); and waitFlush = true and waitSearcher = true.
Source as follows:
/** * Performs an explicit commit, causing pending documents to be committed for indexing * <p> * waitFlush=true and waitSearcher=true to be inline with the defaults for plain HTTP access * @throws IOException If there is a low-level I/O error. */ public UpdateResponse commit( ) throws SolrServerException, IOException { return commit(true, true); }
The above resistance performance of manual commit too, may be used to automatically submit solr configuration.
General also automatically submitted in conjunction with a manual commit to achieve, for example, you want to delete the index rebuild batch can be deleted after a manual commit, then commit batch manually after the establishment of the index.
