- Field query. Target a specific field for searching
- Example: "title:enrollment"
- Results that contain the term "enrollment" in the title.
- When a field query is used, you can use Boolean operators. View a list of fields used out of the box.
- Example: title:enrollment AND group:5
- Fields not recognized will be ignored and default to standard processing.
- Example: "title:enrollment"
The query processing in Solr is extremely configurable. Verint Community uses Solr's EDisMaxRequestHandler for most queries. For non-field searches, the term(s) queried are searched across the title, body, tag and attachment text. The default behavior is for a number of matches terms in the document to be strict at lower counts and get more relaxes as the number of terms increase (see the "mm" configuration setting for an explanation). Community ships with a settings of:
- 1-2 terms, all terms must exist in the document
- 3 terms, at least two of the three terms must exist in the document
- 4-9 terms, 75% of any of the terms must exist in the document
- 10+ terms, 66% of any of the terms must exist in the document
When you search for the term "class enrollment", Solr (technically the EDisMaxRequestHandler) will take responsibility for building a query based on the handler configuration and return documents that match the specified terms. The EDisMaxRequestHandler configuration is the best place to start if you want to tune queries.
