  // A field query is in the form FIELD:QUERY. This implicitly checks if QUERY
  // exists as a substring within Feature's FIELD. The QUERY
  // and the FIELD are converted to a sequence of words (i.e. tokens) for
  // comparison. This is done by:
  //
  //   * Removing leading/trailing whitespace and tokenizing the search value.
  //   Characters that are not one of alphanumeric `[a-zA-Z0-9]`, underscore
  //   `_`, or asterisk `*` are treated as delimiters for tokens. `*` is treated
  //   as a wildcard that matches characters within a token.
  //   * Ignoring case.
  //   * Prepending an asterisk to the first and appending an asterisk to the
  //   last token in QUERY.
  //
  // A QUERY must be either a singular token or a phrase. A phrase is one or
  // multiple words enclosed in double quotation marks ("). With phrases, the
  // order of the words is important. Words in the phrase must be matching in
  // order and consecutively.
  //
  // Supported FIELDs for field-restricted queries:
  //
  // * `feature_id`
  // * `description`
  // * `entity_type_id`
  //
  // Examples:
  //
  // * `feature_id: foo` --> Matches a Feature with ID containing the substring
  // `foo` (eg. `foo`, `foofeature`, `barfoo`).
  // * `feature_id: foo*feature` --> Matches a Feature with ID containing the
  // substring `foo*feature` (eg. `foobarfeature`).
  // * `feature_id: foo AND description: bar` --> Matches a Feature with ID
  // containing the substring `foo` and description containing the substring
  // `bar`.
  //
  //
  // Besides field queries, the following exact-match filters are
  // supported. The exact-match filters do not support wildcards. Unlike
  // field-restricted queries, exact-match filters are case-sensitive.
  //
  // * `feature_id`: Supports = comparisons.
  // * `description`: Supports = comparisons. Multi-token filters should be
  // enclosed in quotes.
  // * `entity_type_id`: Supports = comparisons.
  // * `value_type`: Supports = and != comparisons.
  // * `labels`: Supports key-value equality as well as key presence.
  // * `featurestore_id`: Supports = comparisons.
  //
  // Examples:
  //
  // * `description = "foo bar"` --> Any Feature with description exactly equal
  // to `foo bar`
