Mastering solr
- 1. Mastering solr Jur de Vries
- 2. Who am I? Developer/architect at Triquanta Trainer at Wizzlern
- 3. Use case Market place Advertisements Adjust relevancy Paid boosting of add's Of course we use Drupal and Apache Solr
- 4. Running Solr Locally Download latest version (3.6) Be sure to download distribution (not src) Unpack solr Go to example directory Run java -jar start.jar
- 5. Drupal: which contrib? 2 Possibilities Apachesolr search Search api with solr backend
- 6. Apache solr search Streghts: Supported by Acquia Easy to set up Mature Weaknesses Integration with views (still in dev)
- 7. Search Api Strengths Flexible Indexes all entities Excellent views integration Related fields are easy to add to index Weaknesses Not supported (yet) by Acquia Solr backend has some issues
- 8. Drupal: which contrib? Apachesolr search integration Quick setup Acquia Search API Exportable configuaration Views integration Index all entities Depends on your needs
- 9. Basic use of search api Create server Create index Select fields to index Define data alterations Define processors Start indexing
- 10. Field types Integer, date, boolean String or fulltext? Fulltext will get processed! Tokenize Stopwords Ignore case String is as is
- 11. Demo Run solr Copy schema.xml and solrconfig.xml (!) Create server Create index Create view ads Ad filter exposed: search
- 12. Advanced use of Search api This talk is about Solr, not about search API Understand Solr first! Many resources on the web Watch screencasts etc
- 13. Mastering Solr Mastering solr is understanding solr What happens after a Drupal module? Let's have a look at the request
- 14. Solr request Look at solr log Parameters: start rows q (query) qf (query fields) fl (fields) fq (filter query)
- 15. Field names item_id, id t_.., ss_.., → why? Solr has to know how to handle fields Field api: field names differ Dynamic field names: tell solr field type!
- 16. Schema.xml Defines field types and fields The real tweaking starts here! Let's have a look! dynamicField field type analyzers Copyfield
- 17. What can you do in schema.xml? Synonyms (is disabled by default) Stopwords (and, or, etc) Stemming Proper multilingual handling
- 18. Browse the schema Solr offers schema browsing Go to: http://localhost:8983/solr/admin
- 19. Search relevancy Types of boosting: Field level boost Boost function Boost query (QueryElevation)
- 20. Boost parameters Field level boosting: qf qf:t_body^20 score in field is multiplied by 20 Boost function: bf bf:product(fieldname, 2) result of function is added to score Boost query: bq boost (only for edismax) like bf but multiplication
- 21. Let's boost title Field level boost is incorporated in Search API... But, where are the numbers in the request??? Search api solr forgot to add them! There is a patch :-) But lets do it another way...
- 22. Debugging Solr Lets add &echoParams=all to the request... Where do all these parameters come from? Solrconfig.xml!!! Among other things: request handler Let's look at the dismax request handler
- 23. Solrconfig.xml (Default) Request handler: Default parameters Add Spellcheck Tweak all kinds of search behavior! Let's add default search fields with boost
- 24. Boost function Mathematical functions on field values Available functions: sum(x,y): x + y product(x,y): x * y scale(x, minTarget, maxTarget) recip(x, m, a, b): x / (m * a + b) ms(): time → ms(NOW/DAY, created) Many more!
- 25. Boost date We need ms(): big values! Linear? To much difference Recip! recip(x,1,1000,1000) if x 1000: half 1 year: 3.1e10 recip(ms(NOW/YEAR?, created),1,3.1e10,3.1e10) bf=recip(ms(NOW/YEAR?, created),1,3.1e10,3.1e10)^3 Use a graphing tool!
- 26. Boost queries Do a query like fq: Boost add's: content_type:add bq=content_type:add bq=(content_type)^20
- 27. Debugging relevancy We know how to boost How can finetuning be done? solr has the solutions: add debugQuery=on
- 28. debugQuery=on normal source
- 29. Relevancy Choose your boosting methods Try in your browser Finetuning: debugQuery=on, source Add parameters to solrconfig.xml Or...
- 30. Add parameters in code use hook_search_api_solr_query_alter(array &$call_args, SearchApiQueryInterface $query) $call_args['params']['bq'] = '(t_title:foo)^20' $call_args['params']['bf'][] = b_promote
- 31. Override solr service class In Search API: define server class extend solr service class Only change key methods It's all about passing parameters!
- 32. Conclusion Tweak indexing in schema.xml Stopwords Multilingual Tweak searching in solrconfig.xml Tweak searching by passing variables This is only an introduction!
