[SPIKE] Investigate possibility to search for combine fields

Purpose/Overview:

For now only effective_location + item_status for the same item of instance is considered.

Approach:

Creation of field with aggregation of all values of the particular item as a string concatenation (e.g. i=open;l=some location;m=some material type). This filed should contain array of all such concatenations. The wildcard search for this field should be performed.

Acceptance criteria:

• Viability and performance of such approach should be provided
