Hi, I want to be able to search on special characters e.g. # and $ using the query\_string on multiple fields. I have used the default standard analyzer, which caused some issues (es exceptions) when using for instance ~ in the query\_string. I have subsequently escaped the characters. The problem is that some of the candidates in my index has for instance # in their name, but I need to be able to query for something like n#ame\* where name can be e.g. n#meA, n#meB etc. Which analyzer is best suited for this scenario?

Hey, you may want to install the inquisitor plugin (or use the analyze API directly) and play around with the existing analyzers in order to find out, if an existing analyzer fits your need. Also you can create your own ones pretty easy, see more at > **[GitHub - polyfractal/elasticsearch-inquisitor: Site plugin for Elasticsearch...](https://github.com/polyfractal/elasticsearch-inquisitor)** > > Site plugin for Elasticsearch to help understand and debug queries. - GitHub - polyfractal/elasticsearch-inquisitor: Site plugin for Elasticsearch to help understand and debug queries. > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

Hi Alexander thanks for the feedback, I have installed the plugin and it works great. Thanks for the tip.
