I've used the search api provided by Elastic, I have a question while searching and leave a question.
Why can't I search for "=" or "+" ... etc when searching in Elastic?
If I search for "+abc=", only abc is highlighted.
Among the APIs provided by Elastic, I used BoolQueryBuilder and QueryStringQueryBuilder in java
In addition, I replaced it with "(backslash)=" to search for "=", but to no avail.

Hi
The standard analyzer will remove punctuation in your text.
You can get more info at [Analysis and Analyzers | Elasticsearch: The Definitive Guide [2.x] | Elastic](https://www.elastic.co/guide/en/elasticsearch/guide/current/analysis-intro.html)
