How to search xml data precisely

Elastic Stack Elasticsearch
1

We have an es index storing some xml data.
With the english analyzer, the angular brackets will be treated as stop words. Searching "value" equals searching "element value".

How can I manage to search with the angular brackets?

Thanks in advance.

Hey,

have you thought converting this data to JSON, so you can search for single fields?

The xml filter plugin from logstash might be a good choice. You could setup logstash with an elasticsearch input to gather the data, modify it, and then store it back in ES, like a reindexing operation.

If you try to parse and analyze XML manually, you will run into so many corner cases and specialtes, I dont think it will save you any time in the long run.

Hi Alex,

Thanks for your suggestion. That would be a solution. But not suitable for our case. Actually, the XML data is a kind of our logs, which need be kept its original format.

Maybe I should ask in another words, that, how to do the full-text search while keeping the angular brackets.
