[OpenGuides-Dev] Search and search syntax

by Earle Martin

Here's a log of a conversation Ivor and I had on IRC the other week about searching - meant to post it before, but forgot. Comments? Cheers, Earle. 00:09 -!- Irssi: Starting query in perl with ivorw 00:09 <ivorw> Hi, I've been thinking about how to restructure the search on OG 00:12 <hex> hi. 00:12 <hex> oho? do go on... 00:13 <ivorw> I'm thinking that we keep the existing idea of priming a page cache that is then searched 00:14 * hex nods 00:14 <ivorw> However, the cache can be primed with pages resulting from an SQL query, in addition to those from a keyword inverted index search 00:15 <ivorw> The idea is that including locale=camden causes all locale camden pages to be loaded into the cache 00:16 <ivorw> But a full and & or syntax is available for applying to the cache 00:17 <ivorw> I'm now looking for a syntax for metadata qualifiers on a search 00:19 <hex> hmm... so the search would be faster because locale camden would be cached? 00:20 <ivorw> hex, not quite - the search tree only works over a single hash (cache). The idea is that everything that could possibly match the search is pre-loaded into the cache. 00:21 <ivorw> Prior to O/G, the usemod search worked by slurping the whole wiki into the hash every time. 00:22 <hex> blimey 00:22 <ivorw> Although this works, SII et al provide a better mechanism for subsetting the data, and something that will not blow the server up with a substantial query and dataset 00:23 <hex> right, yes. 00:23 <ivorw> My bodge (which works prety well) is to 'prime' the input hash with the results of an inverted index search on all of the keywords supplied - regardless of and/or syntax 00:24 <ivorw> However, only the SII is used, so the search will only find words in the body text of the page, not in the metadata 00:25 <hex> so we need a mechanism for searching metadata? 00:26 <ivorw> I want to keep this idea of a primed cache, and load it with SQL query results, to provide just that 00:28 <ivorw> How about: King's Head&locale=acton&category=real ale 00:29 <ivorw> Or, how about: locale=west end&category=pubs 00:30 <hex> ah, you mean search syntax 00:30 <hex> I quite like Google style 00:30 <hex> King's Head locale:"West End" category:Pubs 00:31 <ivorw> Ah, but are spaces allowed in metadata field names? 00:32 <hex> I dunno, but surely that could be handled without the user being involved... 00:32 <hex> s/ /_/g on the fly sort of thing and vice versa 00:33 <ivorw> Just thinking that some syntax might be tricky or ambiguous 00:34 <ivorw> the last post code:foo #Is this matching on post code or code? 00:35 <hex> oh, right! 00:35 <hex> no, I think all metadata is one word 00:36 <hex> there could always be a pidgin syntax for it anyway 00:36 <hex> phone:12345 00:36 <ivorw> taken from google again (dig them pidgeons :) 00:37 <ivorw> If we can name every meta field with \w chars, this will be OK 00:38 <ivorw> We could have aliases, phone, telephone, tel, etc. 00:39 <hex> yup! 00:39 <ivorw> Given my previous suggestion, I would quite like to be able to do regexp matches 00:40 <ivorw> e.g. king's head&post_code=~W3 00:41 <hex> must the search terms be joined by '&'? 00:42 <hex> I would have thought a magic word would suffice, or the = 00:42 <ivorw> that was just my previous syntax. 00:42 <hex> ah, I follow. 00:42 <hex> but yes, regexen++ 00:44 <ivorw> How about dropping the &s: locale=west end category=pubs distance(530546,181503)<200 00:45 <ivorw> Note, that's the grid ref of Holborn tube 00:46 <hex> I prefer colons to equals, simply because I think people are more used to Google style 00:46 <hex> but that may just be me 00:47 <ivorw> How about colons for a straight match, and =~ for a regexp 00:47 <hex> "west end" would need quotes so you don't search for "end" in "locale:west" 00:47 <hex> yes, that sounds great. 00:48 <ivorw> might want to delimit the regexp 00:48 <hex> actually, could it be :~ for a regexp, for consistency? 00:48 <hex> I know that's not very perlish.... 00:48 <ivorw> yup, why not tho 00:48 <hex> cool. 00:49 <ivorw> what do you think of my idea of a distance 'function'? 00:51 <hex> how about: 00:51 <hex> near:530546,181503 range:200m 00:51 <hex> a little easier to read 00:51 <hex> (and write) 00:51 <hex> I love the idea 00:52 <ivorw> with a default range presumably 00:52 <hex> hmm, yes 00:52 <hex> units: m, ft, yds, mi, km 00:52 <hex> (maybe) 00:53 <ivorw> Didn't someone give a talk on a module to handle dimensions? 00:53 <hex> dunno :) 00:53 <ivorw> I recall one last year in State51 00:54 <ivorw> Alex Gough: - Meaningful Strong Typing with Data::Dimensions 00:55 <ivorw> unfortunately, the link for the slides is broken :( 00:55 <hex> bug him on the list:) 00:55 <hex> listen, I must run, or rather sleep, my eyes are closing 00:56 <hex> this is very promising stuff 00:56 <ivorw> OK, noe wurriz - Thanks for the braindump receptacle 00:56 <hex> no problem! 00:56 <hex> seeya... 00:56 <ivorw> nn -- # Earle Martin http://c2.com/cgi/wiki?EarleMartin $a="f695a9a2176a7dd1618af6649896ee10f05ea986de18af6277e9a1d8ef4696644569a1d".

[OpenGuides-Dev] [bug-OpenGuides@rt.cpan.org: [cpan #3916] Config.pm leaks database password]

by Kate L Pugh

I just got this very justified bug report. The entire install procedure really needs overhauling. Can I have a volunteer to spearhead this, please? If I don't get one within a week then I'll ask around more widely. Please don't volunteer unless you are committed to producing some real changes within, say, two weeks of starting. I'm feeling the need to expand the team anyway since the workload does seem to be getting greater than we can manage in a reasonable timeframe. I am feeling the burden falling quite heavily on me, and this is meant to be a team effort.

by Ivor Williams

Earle, The rather irritating bug whereby tables generate loads of blank lines, has been fixed in the latest CGI::Wiki::Formatter::UseMod Kake is running the Vegan Oxford site with this version in there, and it's working fine. Can we please fix the London site (and any others). Thanx, Ivor.

[OpenGuides-Dev] Config file location code

by Jody Belka

Accidentally sent this to the cgi-wiki list. doh!! As promised to Kake last night, I've written some config file location code that isn't specific to my installation. Can people take a look and see what they think please? Jody

One of the effects will be reducing our dependence on the SII. In fact category and locale searches will not use the SII at all. If there are any problems with querying the inverted index (rather than updating it), I would be interested and willing to assist, especially as I know exactly how supersearch uses it. Ivor.

I've released 0.24 to CPAN now. The Vegan Oxford guide is running on it, and I think hex plans to upgrade London today. Kake

[OpenGuides-Dev] Supersearch

by Kate L Pugh

I'm *sure* I already sent this, but I can't find it in my outbox. Ivor, I have ripped out the supersearch.cgi stuff into a module OpenGuides::SuperSearch, and added tests. Can you take a look at it ASAP as I don't like the search on london.openguides being broken, so I'd like to do a new release in the next few days. Kake

[OpenGuides-Dev] Wiki zen garden

by Kate L Pugh

[cced to OpenGuides and CGI::Wiki dev lists - Matt, please feel free to join either or both of these. URLs at bottom of mail.] Hi Matt, Paul Mison pointed me at your post about wikis: http://a.wholelottanothing.org/archives.blah/007391 Sounds like you might be interested in some stuff I've been writing. CGI::Wiki is a perl distribution (available on CPAN) that provides a backend for wikis and wiki-like applications. Despite the name, it does no CGI whatsoever - it just stores, indexes and retrieves content and metadata. >From the start of my work on CGI::Wiki I wanted to make it generic enough to be used in as wide a variety of situations as possible. There's a choice of backends (currently MySQL, Postgres and SQLite, but people have expressed interest in writing a flat-file backend too), and since it's a toolkit - providing methods - rather than an actual application, you can use it wherever you like. OpenGuides (also available on CPAN) is built on top of CGI::Wiki. It's a complete web application providing a management system for a collaboratively-written city guide. The London install is currently the largest - see http://openguides.org/london/ Other installs are linked from http://openguides.org/ OpenGuides uses CSS and the Template Toolkit and our aim has always been to produce something completely suited to its purpose, rather than shoehorning our content into something that looks and smells like every other wiki site out there. It does RDF too, so it's all semantic and stuff. Both CGI::Wiki and OpenGuides are in active development. They're certainly not what I would call mature yet, but they're definitely usable. Here are the links for the dev lists: http://www.earth.li/cgi-bin/mailman/listinfo/cgi-wiki-dev http://realprogrammers.com/mm/listinfo/openguides-dev And the code is on CPAN: http://search.cpan.org/author/KAKE/ Kake
