Hi again friends,
Following the release of org-ql 0.5, I've pushed a new feature to the
0.6-pre branch: custom predicates. You can now easily define custom
predicates to make searching easier. For example, you could define a
custom (person) predicate like so:
#+BEGIN_SRC elisp
(org-ql-defpred person (name)
"Search for entries with the \"person\" property being NAME."
:body (property "person" name))
#+END_SRC
Then you could do a search for entries in your agenda files having the
property "person" with the value "Bob" like this:
#+BEGIN_SRC elisp
(org-ql-search (org-agenda-files) "person:Bob")
#+END_SRC
Please see the tutorial for a walkthrough of the process of building a
custom predicate incrementally:

Thanks,
Adam
