"Suggest" (from data) for query creation

[stranak]

Feature just like "Suggest" in PML-TQ web, which allows a user to pick nodes in a tree in search results (words in a concordance line, in case of Kontext), visualise the nodes (words) with all their attributes and pick the ones that should be part of the new query.

See e.g. http://hdl.handle.net/11346/PMLTQ-ELDJ, execute the query and click on some nodes in a resulting tree. Suggest button will be enabled. Just imagine concordance lines and different attributes.

Inspired by Roald Eiselen at LREC.

This is a nice feature, especially for a complex query language. I am just not sure how often would users actually need to use it, but we will think about it.
