[BUG] Missing underscore in from_ documentation args

[josepdecid]

What is the bug?

The documentation for the from_ arg in OpenSearch Client doesn't show the underscore suffix for the following methods:

• search
• update_by_query
• delete_by_query

Checking the args docstrings we can see that all from_ args have an underscore at the end (search, update_by_query, delete_by_query). However, the documentation renders from:

This is very misleading as it's the only arg with an underscore at the end, but other args with underscore prefixes or between words seem to work as expected. If we try to use just from it raises an error:

OpenSearch.search() got an unexpected keyword argument 'from'

It's probably some issue when generating the docs from the docstrings.

What is the expected behavior?

Docs show from_ instead of from.
