* Give advancedTextSearch all search terms at one
The additional conditions for assets had some problems, since they were joining tables for the additional attributes. The method was called once for every search term, so the join was added multiple times if the user entered multiple search terms.
* Allows search to handle multiple search terms better
The search now better handles multiple search terms, adding additional orWhere clauses, instead of duplicating all queries.
* Fixing typo
* Adds the ability to search by dates
Adding extra „where“-conditions to the „TextSearch“ queries, allowing the users to search by dates
* Adds missing dates to $dates in models
* Removes duplicated „where“ conditions
* Adds the Searchable trait to models, defining the searchable attributes and relations
* Removes the old text search methods
* Adds back additional conditions to the search
These conditions could not be modeled in the „attributes“ or „relations“, so we include them here
* Removes unnecessary check for the deleted_at attribute
* Fixes typo in comments
* suppresses errors from Codacy
We can safely ignore the error codacy is throwing here, since this method is a standin/noop for models who need to implement more advanced searches
