The log messages that appear unclear and erroneous

Hello,
i want to ask.
Every time when searching with letters in the logs the errors appear as below:

webapp.log

[2021-05-06 06:58:55][ERROR ] — [Search Framework Rest]: invalid literal for int() with base 10: ‘word’ (search_routes.py)
[2021-05-06 07:01:28][ERROR ] — [Search Framework Rest]: invalid literal for int() with base 10: ‘m4435fd233’ (search_routes.py)
[2021-05-06 07:02:25][ERROR ] — [Search Framework Rest]: invalid literal for int() with base 10: ‘letter and 1234567890’ (search_routes.py)
[2021-05-06 07:17:30][ERROR ] — [Search Framework Rest]: invalid literal for int() with base 10: ‘g’ (search_routes.py)

Why is it only possible to search by integers and then not got errors and there are already errors for letter searches?

and this also from webapp.log

webapp.log

[ERROR ] — [Search count]: Regular expression is invalid: unknown property name after \P or \p, full error: {‘ok’: 0.0, ‘errmsg’: 'Regular expression is invalid: unknown property name after \P or \p
', ‘code’: 51091, ‘codeName’: ‘Location51091’} (search_routes.py)

also error from search but now concerns regular expression

when job from exportd working i got errors:

exportd.log

What is mean ‘value’ for administrator datagerry like me? It should indicate the exact place where there is something incorrect such as the object id number and the field that does not match it or something similar that will help to solve the problem with such errors in the future
