Replacing Jackson to alternative / configuring mapper or other Java objects / upgrading to newer versions of ElasticSearch are not extreme solutions for me if there is example or DevDocs. I also created a question about this issue on StackOverflow |

It looks like escaping the backslash to make the request valid JSON will work, that said, this does not appear to be an elasticsearch bug and is a question more appropriate for the forum at https://discuss.elastic.co |

Description of the problem including expected versus actual behavior:
On Magento 2 (where ElasticSearch is default option) I have an issue that is quite difficult to identify. And I would like to create the issue on Magento2 github project, but unfortunately I do not have valid steps to reproduce. But so far I have steps to reproduce here.
Let me show you my blurry understanding of the problem:
There is a string "Pris per fp. ." (not only this, there are others that share the same feature). It has a dot and a space that is preceding a dot and even one more dot before. My guess is that somewhere between PHP and MySQL and Elastic there is a misunderstanding about one of these suspicious sequences:
The shop is selling different details like screw drivers or for example screen replacements. So even this
2.5x3.2.is potential issue. I am still in process of bug investigation. Now let't go back to Elastic related stuff.Steps to reproduce:
Please include a minimal but complete recreation of the problem,
including (e.g.) index creation, mappings, settings, query etc. The easier
you make for us to reproduce it, the more likely that somebody will take the
time to look at it.
Expected result:
{ "query": { "query_string": { "query": "." } } }' { "took" : 0, "timed_out" : false, "_shards" : { "total" : 0, "successful" : 0, "skipped" : 0, "failed" : 0 }, "hits" : { "total" : 0, "max_score" : 0.0, "hits" : [ ] } }Actual result:
{ "query": { "query_string": { "query": "\." } } }' { "error" : { "root_cause" : [ { "type" : "json_parse_exception", "reason" : "Unrecognized character escape '.' (code 46)\n at [Source: org.elasticsearch.transport.netty4.ByteBufStreamInput@581be1c5; line: 5, column: 19]" } ], "type" : "json_parse_exception", "reason" : "Unrecognized character escape '.'

On production I see these logs
