Declaration

public Search.IQueryEngineFilter AddOrUpdateMetaInfo(string key, string value);

Parameters

key The key of the information.
value The value of the information.

Returns

IQueryEngineFilter The current filter.

Description

Add or update additional information specific to the filter.

You can use this function to add additional information on the filter.

// Add a description to the filter
var descriptionKey = "desc";
var descriptionValue = "This filters the objects based on their id.";
var exampleKey = "example";
var exampleValue = "id>10 or id=2";
queryEngine.TryGetFilter("id", out var filter);
filter.AddOrUpdateMetaInfo(descriptionKey, descriptionValue)
    .AddOrUpdateMetaInfo(exampleKey, exampleValue);

You can then retrieve that information by accessing the metaInfo property directly.

var descriptionKey = "desc";
var allFilters = queryEngine.GetAllFilters();
var filtersWithDescription = allFilters.Where(f => f.metaInfo.ContainsKey(descriptionKey));

See metaInfo for a complete example.
