Thank you.

Are you saying that queries are turned into regexp searches within Org
files? If so, I don't think they should. 

Queries should only operate on the output of the data extraction,
possibly a list of defstructs. I.e., you first extract all meaningful
data from the document (during idle time, with cache, or whatever
optimization would be chosen), store it in an appropriate format, then
query it.

WDYT?
