Allow wide search in the OSSR through ESAP gui

At the moment, the search can be down-selected only using keywords. Is this a desired feature? Keywords are a great way to categorize records, but maybe not the most straightforward way to search them, especially for a newcomer that will have no idea of the keywords used in the OSSR.

A simple wide text search is possible though and would be more appropriate in my opinion. For example, a search for the word gamma currently returns two records: https://zenodo.org/communities/escape2020/search?page=1&size=20&q=gamma

While a search using the keyword gamma returns none: https://zenodo.org/communities/escape2020/search?page=1&size=20&q=&keywords=gamma

Note: For some reason, I can't open an issue related to the esap-gui project ?
