Advanced Search

The advanced search lets you filter expertisers by specific criteria. Use search qualifiers in the form qualifier:value – similar to Google or Gmail search.

Available Qualifiers

Qualifier	What is searched	Example
name:	First and last name of the expertiser	`name:müller`
city:	City or place of activity	`stadt:berlin`
country:	Country of the expertiser	`land:germany`
firm:	Company or office name	`firma:philatelia`

Expertisers named "Schmidt" in the Germany area


                stadt:berlin form:oval

Notes

— Case insensitive: name:mueller also finds "Mueller"
— Partial words work: name:huy finds "Huylmans"
— Queries without qualifier syntax work as plain text search (existing behaviour)
— Multiple qualifiers are combined with AND – an expertiser must match all conditions
