Multiselect search filter is created with the wrong comparison mode

Symptoms

When adding a front-end search filter by a custom field and selecting to display it as a multiselect control, the associated query filter is created with a comparison of equal to. Because of this, when selecting more than one option, the search value is wrong and no results are returned.

Workaround

This issue will be fixed in the upcoming version of Toolset Views, and there is no patch for it.

However, as a workaround, you can simply edit the associated query filter and make sure that its settings state that:

• The field XXX is a string that is IN the following: URL parameter YYY.
