createArrayFilter	The function takes filter value as an input and returns a filtered array
createFilter	The function takes filter settings as an input and creates a filter
createFilterRule	Creates a common filtering rule for several input fields
getFilter	The function retrieves a filter configuration object based on the provided filter id and type
getFilters	Fetches a list of available filters
getOptions	The function returns the list of options for a specified field
getOptionsMap	The function extracts filtering options for multiple fields at once

The following functions are used only for the FilterQuery component:

getQueryHtml	Converts a FilterQuery query string into an HTML string with inline style spans for syntax coloring.
getQueryString	Converts a rules configuration object back into a FilterQuery query string.
