 ====== Indexing of the CERL Thesaurus ======
 This page is still under construction...
+===== Available Search Fields =====
 The CERL Thesaurus comes with a complex index that allows for sophisticated searches. The following search fields are available:
@@ Line 52: / Line 55: @@
 |year_end|yes|standard|date|340$x|search for entities whose activity or existence ended before, in or after a certain year \\ ''year_end:>1800'' \\ year_end:<1500|
 |year_start|yes|standard|date|340$x|search for entities whose activity or existence started before, in or after a certain year \\ ''year_start:[1530 TO 1560]''|
+In addition to these searchable fields, the index contains the followin fields, which cannot be searched, but are used to generate the result set display:
+|additional_display_line|additional information on the entity|
+|name_display_line|name of the entity|
+===== Searching Relationships =====
+A number of the search keys listed above allow to retrace the relationship between the entities described in the CERL Thesaurus. It is assumed that one part of the relationship is known, e.g. a person or a place and using this person's or place's id, we can retrieve the records that link back to it.
+For example: Knowing the ID for the place "Tübingen", we can retrieve persons who went to university here: ''studied_in:cnl00014526''
