Search does not find some inline code

[n01r]

Describe the bug

When searching the RTD of the WarpX project, sometimes no results are found even though there are matching parts of the documentation but the string is inside a code-block/region.

How to Reproduce

For example, the search for BeamRelevant yields no results:
https://warpx.readthedocs.io/en/latest/search.html?q=BeamRelevant&check_keywords=yes&area=default
However, there is a matching string here
https://warpx.readthedocs.io/en/latest/usage/parameters.html

This search, on the other hand, yields a result and the match is inside inline code
https://warpx.readthedocs.io/en/latest/search.html?q=ParticleHistogram&check_keywords=yes&area=default#

1. Downloading the code
2. Building the documentation

Expected behavior

I would expect to be able to find all matching documentation, even when inside a code block.
