As the minimum_should_match is set to 1 either the name of the product can contain the string t-shirt or the color can be option id 16. Elasticsearch uses Apache Lucene internally to parse regular expressions. Lucene converts each regular expression to a finite automaton containing a number of determinized states. You can use this parameter to prevent that conversion from unintentionally consuming too many resources. When a special character is adjacent to a stop word in a query, the stop word is not removed from the query.

For example, searching for at&t does not remove the stop word at. I have corrected it now. I You should look into using ngram or edge ngrams to improve the speed issues. According to this document: https://www.elastic.co/guide/en/elasticsearch/reference/2.3/query-dsl-query-string In your case you are querying against a field with a text datatype ,as written in your Y foo&bar123 (an exact match) foo & bar123 (white space between word) foobar123 (No >special chars).

I have some similar use case below. The query_string query provides a means of executing multi_match queries, bool queries, boosting, fuzzy matching, wildcards, regexp, and range A query string query is an advanced query with a lot of different options that ElasticSearch will parse and transform into a tree of simpler queries. A full Setting the minimum_should_match to 100% would require all the conditions to match.. Another way to achieve this is via a must.All conditions provided as musts must match (as If you index a document to Elasticsearch containing string without defining mapping to the fields before, Elasticsearch will create a dynamic mapping with both Text and Keyword data type. I would suggest to use them over query_string query for instance, which is a lot Search: Elasticsearch Regex Query String. Elastic Stack Elasticsearch.
