Filter collection items with a string contains instead of equal

I’m submitting a Feature request

Motivation / Use Case

Hi!

My oData backend returns a field that holds a comma delimited string of values: [{ roles: 'User,Sales,SuperUser' }].

I’m presenting this in the grid with a formatter that displays each value as a (bootstrap) badge 📛. Nice!

Ultimately I want to be able to search with a (custom) multiselect FilterControl on any combination of the values.

Now at first I started with a single select and because searching for User shouldn’t return SuperUser I added a , to the query field and each queried value and use a ‘contains’:

	queryFieldFilter: 'concat(roles, \',\')',
	filter: {
          collection: [
            { value: 'User,', label: 'User' },
            { value: 'Sales,', label: 'Sales' },
            { value: 'SuperUser,', label: 'SuperUser' },
          ],
          operator: OperatorType.contains,
          ...

This works and $filter=contains(concat(roles, ','), 'User,') is send to the oData backend. 😀

The next step is to get the multiselect working and I noticed OperatorType.inContains which sounds like it fits my need, but IN_CONTAINS isn’t implemented: https://github.com/ghiscoding/Angular-Slickgrid/blob/master/src/app/modules/angular-slickgrid/services/grid-odata.service.ts#L352 😢

Now I’m not completely sure what the purpose of IN_CONTAINS is and I’m wondering if it can be used and if I can implement it roughly like:

	...
	else if (operator === 'IN_CONTAINS') {
		for (let j = 0, lnj = searchTerms.length; j < lnj; j++) {
			const s = odataVersion >= 4 ? `contains(${fieldName}, ${searchTerms[j]})` : `substringof(${searchTerms[j]}, ${fieldName})`;
			tmpSearchTerms.push(s);
		}
		searchBy = tmpSearchTerms.join(' or ');
	...

or if there would be a different direction/solution perhaps? 😄

What do you think?

Expected Behavior

IN_CONTAINS can be used in oData and other backends.

@ghiscoding I’ll migrate to 3.x first and will then create an issue or PR on the new repo.

The try statement consists of a try-block, which contains one or more statements. {} must always be used, even for single statements. At least one catch-block, or a finally-block, must be present. This gives us three forms for the try statement: try…catch try…finally try…catch…finally
