<pre>
A list of keys of filterable
[Profile.custom_attributes][google.cloud.talent.v4beta1.Profile.custom_attributes],
whose corresponding `string_values` are used in keyword searches. Profiles
with `string_values` under these specified field keys are returned if any
of the values match the search keyword. Custom field values with
parenthesis, brackets and special symbols are not searchable as-is,
and must be surrounded by quotes.
</pre>

<code>repeated string keyword_searchable_profile_custom_attributes = 4;</code>

@param index The index of the value to return.
@return The bytes of the keywordSearchableProfileCustomAttributes at the given index.
