There are many factors to bring up best implementation of Enterprise Search in Search world. However few elements are taken into consideration while preparing Solr solrconfig.xml & schema.xml for Core. Why I’m calling below points as top 10 performance tips? As I said many factor drives the performance, however below points are must to have during a installation; that’s why 🙂
Below listed tips contribute towards good to start configuration and better performance on Apache SOLR [Enterprise Search] for your search implementation
- Master {for Indexing more information} and Slave {for querying more information i.e., application interaction. Multiple slave instances based on need} installation on Apache SOLR
- Focus on Solr schema field definition
- define stored=”false” for all fields possible (particularly large fields) when you required to do a search on the field and not to return the original value
- On the other hand set indexed=”false” if required to return the field as search result on other indexed fields and not required to do a search on the field.
- Use copyField on need basis
- Use dynamicField when required
- For best index size and searching performance, set “index” to false for all general text fields, use copyField to copy them to one “text” field, and use that for searching
- Use StreamingUpdateSolrServer java client to maximize indexing performance ratio
- Run SOLR server JVM in “server” mode. For e.g.: provide “-server” in JVM option
- Use tint, tlong, tdate, tdouble, tfloat for faster range queries
- Use High Level Logging instead of every request on SOLR server side
- Disable “autoCommit” on solrconfig.xml
Above key factors will contribute towards betterment of your Solr search configuration. I will try add other factor for facets, auto suggests, spellcheck dictionary, etc.
