advanced search for patterns

advanced search for patterns

[hj-orgmode-1]

hello, I have been using orgmode for a while , and noticed that I can 
find headings based on tags, but I haven't figured out whether there is 
a way to say in emacs org-mode :

   find me all the (lowest-level) headings [ or heading-paths ] that 
contains text (whether formatted as source code blocks or whatever) that 
matches, say three, (regexp) patterns, e.g. :

    (M|m)artha
    ((buy|bought)[^\n]*milk(s?))
    (pay|paid|USD)

  How would one ask org-mode to find all such headings (in all opened 
org-mode buffers , preferably :) )

  I guess one could try to connect the three regexps with something like 
a negative-lookahead "does not contain '\n\*'" string, like

    (M|m)artha (:!\n\*){0}   ((buy|bought)[^\n]*milk(s?)) (:!\n\*){0}   
(pay|paid|USD)  |  \
    (pay|paid|USD)  (:!\n\*){0} (M|m)artha (:!\n\*){0} 
((buy|bought)[^\n]*milk(s?))    |  \
    ((buy|bought)[^\n]*milk(s?))  (:!\n\*){0}   (M|m)artha (:!\n\*){0}   
(pay|paid|USD)  |  \
    (pay|paid|USD)  (:!\n\*){0} (M|m)artha (:!\n\*){0} 
((buy|bought)[^\n]*milk(s?))    |  \
     ...

  but that's just ugly. And would it work at all? Would it not be so 
slow to make it impractical?

   Or is there a way to say "search all headings for pattern1" in all 
files, then filter the results by pattern2, then filter the results by 
pattern3 ?? How? Someone surely must have done this before ...


    thx!!

with the correct variable settings, i think you can do

  {pat1} {pat2} {pat3} -{pat4}

you can check the manual for the search settings.

correction:

should do the trick iiuc and if you have the varialbe setc.

  Yes Samuel! This does work! Thank you! ( Although I haven't figured 
out yet which variable(s) you might be referring to ... )

you're welcome.

things like (setq org-agenda-search-view-always-boolean t)
(setq org-agenda-search-view-force-full-words t) in manual.
