Dear all
Happy new year!
I have a problem when I use the highlight, I want to highlight a field
'abs' while it contains html, like:
the content of field 'abs':
... The molecule:(L2L3M)n ...
I want to escape the html when highlight and found that the "encoder" option.
I use this option:
```
"highlight": {
"escape_html": "html",
"pre_tags": [""],
"post_tags": [""],
"fields": {
"abs": {
"fragment_size": 150,
"number_of_fragments": 1,
"no_match_size": 150
}
}
},
```
but nothing changed, the html tags like '' still returned untouched.
Any hints of what could be wrong?
Thanks!

Hi,
You try to use parameter "encoder" instead of "escape\_html".
