Dear all,
I'm trying to figure out how to do Properties search by define an agenda
command.
Here is my item in org file:
*** Franz Schwabl / Quantum Mechanics
:PROPERTIES:
:TITLE: Quantum Mechanics
:AUTHOR: Franz Schwabl
:CATEGORY: Quantum Mechanics
:TAGS: Quantum Mechanics, Group Theory
:KEYWORD: Quantum Mechanics, Perturbation, Second Quantization
:LOCATION: iTune
:END:
And I want to define a agenda command to search this item out. I've tried
this one, but did not work:
("19" "TEST" occur-tree "Title="Quantum Mechanics"")
("19" "TEST" tags "Title="Quantum Mechanics"")
So is there anyone knows how to do this correctly?
Thanks,
Chao

The following search works fine for me with the OP's properties drawer: C-c a m TITLE="Quantum Mechanics" > Looks like to use the intended functionality someone has to patch Org > mode's tag search to handle multivalue properties. I don't believe the space in property values is meant to indicate multiple values (i.e., in the same way that ":" separates tags). Here's an example from the manual: --8<---------------cut here---------------start------------->8--- * CD collection ** Classic *** Goldberg Variations :PROPERTIES: :Title: Goldberg Variations :Composer: J.S. Bach :Artist: Glen Gould :Publisher: Deutsche Grammophon :NDisks: 1 :END: --8<---------------cut here---------------end--------------->8--- That said, one can create ad hoc multivalue properties by using regexps in property searches.

Here's > an example from the manual: This is a misunderstanding: Yes, you can use space characters in single value properties and use regexps to simulate multivalue properties. But you can't use Org's multivalue properties (C-h f org-entry-put-multivalued-property RET). Looks like an inconsistency or a glitch: Org supports putting multiple values in a property but has no reserved separator for multiple values. So there is no way for a function recognize multivalue properties -- what makes it hard to perform a search for properties with multiple values w/o having the user enter a regular expression.

AFAICT, the OP was not inquiring about a multivalue search, but rather simply asking how to match an entire property value string (i.e., the title of a book). The problems was caused not by unescaped spaces in property values, but rather by how the custom agenda search was constructed (e.g., incorrect property key, unescaped quote marks, etc.). >> I don't believe the space in property values is meant to indicate >> multiple values (i.e., in the same way that ":" separates tags).

Good to know. I wasn't aware of multivalued properties. I think my comment still stands: currently, for normal tags/property searches, single spaces are not intended to indicate multiple values. The function org-tags-view invokes only the single value property mechanism (i.e., org-cached-entry-get). AFAICT, multivalued properties were introduced to accommodate org-attach but they have not (yet) been used elsewhere in Org-mode. See the following commit: --8<---------------cut here---------------start------------->8--- commit d043e31182595983df3d191e80ca941ee171c400 Author: Carsten Dominik <carsten.dominik@gmail.com> Date: Wed Oct 1 09:25:18 2008 +0200 Integrate John Wiegley's org-attach.el. --8<---------------cut here---------------end--------------->8--- > Looks like an inconsistency or a glitch: Org supports putting multiple > values in a property but has no reserved separator for multiple > values.

Currently, the only way to extract multivalue properties is to use the API functions: (info "(org) Using the property API") I believe single value properties should be the default behavior for searches (that is how the manual presents properties). I would certainly *not* want to have to escape spaces in property drawers when, say, entering AUTHOR and TITLE property values. Currently, the search logic of is relatively straightforward: 1. to force an exact property match, use TITLE="Quantum Mechanics" 2. to allow partial matches, use a regexp: TITLE={Quantum} Perhaps a patch could introduce an user option to use the multivalued API in property searches. This could be a nice option for custom commands. But I would recommend that the single value remain the default. Best, Matt ^ permalink raw reply [flat|nested] 6+ messages in thread

Two things: 1. You need to escape the inner quote marks in the custom command. 2. AFAICT Properties are case sensitive. Your drawer includes a "TITLE" property but your custom command searches for "Title". This custom command worked for me: (setq org-agenda-custom-commands '(("x" "TEST" tags "TITLE=\"Quantum Mechanics\""))) You could also just type the following: C-a m TITLE="Quantum Mechanics" Note: you can also use regexps in property searches. E.g., C-a m TITLE={quantum.*mechanics} Best, Matt ^ permalink raw reply [flat|nested] 6+ messages in thread
