Search Analytics Options Overview
Review wildcard and syntax options that can help to improve Search Analytics Discover operations
Search Analytics and Elastic support some logic options for the search term values. The following table describes different options for search terms that provide some flexibility in values.
Note that Dashboards Query Language (DQL) does not support regular expressions or searching with fuzzy or proximity terms. ChaosSearch does support some regular expressions in Lucene searches.
Lucene Query Syntax
Elasticsearch uses the Lucene query syntax for searches. Refer to query string syntax for more information about constructing your queries.
|Wildcard (*)||The asterisk wildcard character replaces (represents) multiple characters. For example:|
By default, OpenSearch Dashboards does not support leading wildcards for performance reasons, but ChaosSearch supports them.
|Wildcard (?)||The question mark wildcard character replaces (represents) one valid character, number, or symbol. For example:|
When using the single-character wildcard, enclose the wildcard string in double quotation marks.
|Ranges||In a DQL search, you can specify ranges using the range operators |
In a Lucene search, the range format is different. For example:
|Regular expressions||In a Lucene search, the forward slash |
Search Analytics is an embedded version of OpenSearch Dashboards. See the OpenSearch Dashboards documentation for more information about exploring data using Discover.
