CLAIMS® SOLR supports finding words that are a within a specific proximity to one another. To execute a proximity search, use the tilde, "~", symbol at the end of a phrase. For example, to search for "solar" and "generation" within 5 words of each other in a document, use the the following search query:
...
Searches in CLAIMS® SOLR are not case-sensitive. Search terms may be entered in caps or lower case, regardless of case in the documents.
Note: You must enter Operators must in ALL CAPS and enter field names in lower case.
...
- Since the field names are case-sensitive, always use lower case letters
- Capitalize operators (AND, OR, NOT, TO)
- Use straight quotes to enclose phrases. (Note: This is an issue only if you are cutting/pasting from another source where "smart quotes" may have been used.)
...
You can use a filter query to restrict the superset of documents that are returned by the standard query. There are two advantages to using the filter query rather than including the restriction with your standard query: (1) The filter query does not affect score, and (2) It can increase the speed of complex queries since the filter query results are cached.
