One day elasticsearch stopped working properly on my magento. I’ve installed sampledata, ran reindex. I have total 188 products count in elastic. I’m trying to search something with quick search, but it returns me all products in response.

I dived into the code and found that JSON does not contain any information about my query. I see that necessary filter is present, but at some moment – it is disappearing.

Here is my JSON:

{     "index":"magento2_product_1",     "type":"document",     "body":{         "from":"0",         "size":"10000",         "fields":[             "_id",             "_score"         ],         "query":{             "bool":{                 "must":[                     {                         "term":{                             "category_ids":"2"                         }                     }                 ],                 "minimum_should_match":1             }         }     } } 

Same JSON in one row:

{"index":"magento2_product_1","type":"document","body":{"from":"0","size":"10000","fields":["_id","_score"],"query":{"bool":{"must":[{"term":{"category_ids":"2"}}],"minimum_should_match":1}}}} 

As you may notice, it doesn’t have search_term, and as result response is wrong.

Can anybody provide me correct JSON which magento sends to elasticsearch and maybe somebody can direct me why it could happen?
