[Custom Fields] Filter by text and number types

Proposal

Support filtering by text and number types anywhere custom fields filtering is supported.

Proposed UX

• Field selection: User selects field token using standard filter behavior (fields appear using field type icon + field name)
• Operator selection:
  • For text fields, options are "contains" ~= (or just ~, only slight preference for include equal sign), "does not contain" !=, "is exactly" =, "is set" = *, "is not set" != *
  • For number field, options are "is exactly" =, "greater than" >, "less than" <, "is set" = *, "is not set" != *
  • Showing the operator for Is set and Is not set is optional assuming they utilize standard operators + wildcards, as noted below
  • "Is set" applies = plus a wildcard, such as * , as the value which is automatically closed as a token (i.e. user does not have an input step when selecting "exists")
  • "Is not set" applies != and *
• Value entry works similar to text search: no autocomplete is shown, user enters text in the input and on "enter" the token is closed. The search does not apply on token close (existing filtered search behavior).
