描述

Represents a query parsing error.

This class is only used in the context of SearchProviders, when performing a search. It allows a SearchProvider to report error during the parsing of the search query. Here is an example of a SearchProvider that uses a QueryEngine and reports parsing errors:

public IEnumerable<T> Search(SearchContext context, SearchProvider provider, IEnumerable<T> subset = null)
{
    var query = m_QueryEngine.ParseQuery(context.searchQuery, true);
    if (!query.valid)
    {
        context.AddSearchQueryErrors(query.errors.Select(e => new SearchQueryError(e, context, provider)));
        return Enumerable.Empty<T>();
    }

    m_DoFuzzyMatch = query.HasToggle("fuzzy");
    IEnumerable<T> gameObjects = subset ?? m_Objects;
    return query.Apply(gameObjects, false);
}

In the previous example, the function "Search" would be called by the provider's fetchItem.

In the Search window, the errors are shown when there is no result available. .
