Add the possibility to filter by feed ID like `f:123 more-search`
or multiple feed IDs, like `f:123,234,345 more-search` or an exclusion
like `!f:456,789 more-search`
* Implement negation for searching by date intervals
#fix https://github.com/FreshRSS/FreshRSS/issues/2866
Allow searching for e.g. `!date:P1W` to exlude all articles newer than
one week.
More generally, allows exclusion on some date intervals.
* Fix OR
* Tags split improvement
Some feeds use a single category with comma-separated tags.
Better handling of tags containing a space
* Handle spaces in searches with +
Can now search in tags containing spaces
* Fix searches with spaces for title and author
https://github.com/FreshRSS/FreshRSS/issues/1381
Possibility to exclude authors, titles, tags, urls, words by prefixing
them by ! or - (like Google Search):
* !intitle:unwanted
* -intitle:unwanted
* -author:unwanted
* -#unwanted
* -unwanted
And one can use many of each and combine them with positive searches
Before, the search was a single value.
Now it is splited in chuncks when separated by spaces.
Except if they are enclosed by single quotes or double quotes.
For some reasons, the unit tests are working for both single and double quotes but the
search box isn't. It is working only with single quotes.
We need to investigate the reason of this behavior.
See #823
There were multiple calls made to the cleaning method that were unnecessary since it is useful only on the last call.
It allows to simplify code by returning values ealier.
I figured that the code for the search could be extracted from the context to have separation of concern.
It supports multiple keywords. It suports also multiple tag keywords.
