Hello I am trying to save percolator query with code which looks like this ` "query": "Content.\\*:apple OR android"` but i got error response which looks like this `No field mapping can be found for the field with name [Content.*]`. If I try to use search using this exact query it works. And if I will save percolate query with single words endlosed in parenthesis it works too. I did not managed to found any solution nor issue on github or topic in disussion. Here is example of code which I am trying to run and don´t work: ```auto PUT someindex/_doc/333-444-fr { "Percolate": { "TopicId": 444, "MonitoringId": 333, "LanguageCode": "FR", "Query": { "query_string": { "query": "Content.\\*:apple OR android" } } }, "Id": "333-444-fr" } ``` Here is example of code which works: ```auto PUT someindex/_doc/333-444-fr { "Percolate": { "TopicId": 444, "MonitoringId": 333, "LanguageCode": "FR", "Query": { "query_string": { "query": "Content.\\*:\"apple\" OR \"android\"" } } }, "Id": "333-444-fr" } ``` Here is link to documentation which I am using. [[Query string query | Elasticsearch Guide [7.16] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#:~:text=Another%20option%20is%20to%20provide%20the%20wildcard%20fields%20search)]([https://query-string-query](https://query-string-query) documentation) ---

IMO this shoul be considered as BUG ---

What I need to do to send this as a Bug? ---

Can you provide a fully reproducible example including index creation and mapping along with the version that you are using? Thank you! ---

Hello, Thank you for response! Our version of ES is 7.14.2. I wast trying narrow down our business mapping until I came across very first exampple of percolating on [documentation page](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-percolate-query.html). I only changed type of matching documents from terms to query string query. ```auto Create an index with two fields: PUT /my-index-000001 { "mappings": { "properties": { "message": { "type": "text" }, "query": { "type": "percolator" } } } } ``` ```auto Register a query in the percolator: PUT /my-index-000001/_doc/1?refresh { "query": { "query_string": { "query": "bonsai tree" } } } ``` Where I got this (same) error . ```auto No field mapping can be found for the field with name [*] ``` ---

By switching to a `query_string` you changed the query actually. The `match` query only searches in the `message` field, by not specifying a field in the `query_string` query it tries to query all fields, and that is failing. Try using concrete field. ---

Hello, but I am specifiyng `field` in `query` (original post). Either way I think this is bug. What do you think? Thank you ---
