Summary
Product Search uses Elasticsearch's Query String to perform free-text search, as this allows fine control over the search using a basic Query String Syntax.
The table below lists the aspects of the Query String Syntax that are supported (see the Elasticsearch Query String Syntax document for full details).
Table of Contents maxLevel 2
Feature | Example | Description |
OR | canadian bacon | By default multi term searches are OR'd together - i.e find matches that contain either the word canadian OR the word bacon (in any order or position) |
AND | canadian AND bacon | Use the AND/&& keyword if both terms are required (in any order or position) |
NOT | canadian AND bacon NOT film | Use the NOT/!/- keywords for words that must not be present |
Preferred | canadian +bacon | Use the + operator to specify that a term must be present - i.e the work bacon must be present, while th eword the word candian is optional (but will increase relevancy if it is present) |
Grouping | canadian AND (bacon OR ham) | Multiple terms or clauses can be grouped together with parentheses, to form sub-queries |
Wildcards | qu?ck bro* | Wildcard searches can be run on individual terms, using ? to replace a single character, and * to replace zero or more characters |
Regular Expressions | /joh?n(ath[oa]n)/ | Regular expression patterns can be embedded in the query string by wrapping them in forward-slashes |
Fuzziness | quikc~ brwn~ foks~ | You can search for terms that are similar to, but not exactly like our search terms, using the “fuzzy” operator (~) |
Boosting | quick^2 fox | You can use the boost operator (^) to make one term more relevant than another |
