Обсуждение: Let's play bash the search engine

Hello,

search.postgresql.org is now served directly from PostgreSQL 8.2 ,
Tsearch2 and GIN. We have been testing thoroughly for the last couple of
weeks but of course... it is now open to the general public.

Take a look at let us know what you think and how it performs for you.

Sincerely,

Joshua D. Drake

i would love an advanced search where you can limit the results to a
particular version of the documentation. the query for "SELECT" returns too
many results from too many versions, obviously.

its fast & quick tho :-)

+1 there - current docs should be searched unless you specify all/older
docs. Maybe old docs can be included in the archives section, which the
link isn't overly clear that it is the mail archives.

I reckon the old search showed 3-4 lines in the 'preview' of the
listing, now we only get 1 which sometimes wraps partially onto 2.
Personally I preferred having 3-4 lines in the results - it can be
easier to pick out the page that you are searching for without going there.

One thing that I have seen on a few searches (eg. yahoo cached pages) is
when you follow a link it then highlights the search criteria on the
page. Would be a nice feature to quickly find the search result on the
destination page.



I found a little error in the page coding calculations -

Search for create
it states "Pages 1-20 of more than 1000." - that's ok
if you go to page 50 you get "Pages 981-1000 of more than 1000." - fine
then on page 51 you get "Your search for create returned no hits."

search for 'select' or 'update' gets the same thing. It would seem that
you have a 'limit 1000' which gives the 'more than 1000' in the hits
description but it generates an extra page (51) that tries to fetch
1001-1020

You get this if you go into say the 8.2 docs, and use the search form
there - same as before.

That said, it's not a bad idea to add it anyway, but so far the main
concern has been feature-identical to what we had before.

Seems to_tsvecto() returns NULL for tsearch2 or for, as you say,
anything that ends in a digit.

Oleg, can you comment on why this is happening? What can we do to fix
that?

Most probably, token type 'word' just doesn't indexed. If you
didnt' correct this from pgweb configuration:

-- we won't index/search some tokens
update pg_ts_cfgmap set dict_name = NULL
where tok_alias in ('email', 'url', 'sfloat', 'uri', 'float','word')
and ts_name = 'pg';

I think it would be useful to adjust the parser to not split on underscores:

In case I'd like to lookup PG's to_number() function I won't get
anything useful. Number is contained nearly everywhere and to is
configured as stop word. Same with most other functions.

That sounds like it's the problem. I'll update the configuration, and I
assume I have to regenerate all the tsvectors as well, right?

Should I set it to 'simple' or one of the others?

This has now been fixed for both website and archive search. So now you
can search for the technology that made the search possible in the first
place again :-)

//Magnus

Hi,

Seems ok. Works better than most corporate search engines - some tend
to show pages and pages of useless press releases when you are
searching for drivers, specifications etc.

But as long as the sites remain indexable to outside search engines,
people get to use whichever search engine they prefer.

For example: Google works fine with: site:postgresql.org

It also does phrase searches, pdfs (you can even do filetype: inurl:
and other stuff[1]).

Have fun!

Link.

[1] For example: filetype:pdf "company confidential"
or filetype:xls confidential price

I would search from the home page rather than navigate to docs first.
(open browser - type postgres.org (enter) - tab to search field - type
whattofind (enter)

It would seem to be one of those 'accept it as it is' when you get here,
and now that you ask us to look we say 'but why?' ;-)

Yeah, I can see how that's a common usage pattern.

Heh, it was actually Josh that asked you to look ;)

But seriously, I'm definitly interested in ways it can be improved - and
that's true of the whole web team, I'm sure. It was just my way of
saying "it will take a while", but I'll file it away as a good thing to
do when there is a moment of spare time.

I like the way the php.net homepage has a search box on the homepage
with a dropdown next to it to specify what to search.

Yeah, that would be very appropriate, allowing you to search specific
version of the docs.  Heck, if it allowed searching of specific mail
lists, that would rock.

You seriously want this in the header of every webpage?!

We still have a searchform at search.postgresql.org. To search
mainliglists, click Archives search. You can select a list, or a group
of list, there. Or just search them all.

Now, the generic website search could be expanded to let you search
different parts such as the docs, but we cannot possibly do that on the
searchbox in the header.

It should be pretty easy once documents has apropriate metadata.
Also, displaying current section in search box would be informative,
so when you're in current documentation, pull-down menu should display
<8.2 Documentation>.

Definitly worth looking at what we can do without breaking the layout
there.

As for searching spceific mailinglists, you can do that from the
archives search page already. Perhaps it needs to be made more
accessible or something?

Too many check-boxes :) Better to have pull-down menu with multiple selections.

Anyone see any value in allowing the mailing list search to be sorted by
both ascending and descending date?

Checkboxes IMO are a no-op. However a drop down box is probably
reasonable.

I bet HAVING is a stop-word, so actual message is
'NOTICE:  query contains only stopword(s) or doesn't contain lexeme(s), ignored'

I think we should add to pg_dict dictionary line

having having

This will prevent 'having' be recognized as a stop-word by other dictionaries,
which follow pg_dict dictionary.

Would a link to search.postgresql.org by the search box at the top
of each page be enough?

Amazing.  What I like the most about it is that it actually works.
Great!

I think it would be good to make it more prominent.  Maybe have all the
search forms integrated on a single page and put a link to it in the top
menu, next to Support.

just a though... wouldn't it make sense for a documentation search index to
*not* have stop words at all? potentially every word that is being searched
for could be contained in a query example, code piece etc and thus seems
important to me... for example keywords like AND, OR etc.

Ah, I forgot about them. Now, with GiN we could definitely try
stop-words free search !

I think it would be useful to adjust the parser to not split on underscores:

In case I'd like to lookup PG's to_number() function I won't get 
anything useful. Number is contained nearly everywhere and to is 
configured as stop word. Same with most other functions.

well, why not add a dropdown (or even better a multi-select input) on the
search page where users can choose what to search in:

All (default)
Documentation
\_ Most Recent
\_ 8.2
\_ 8.1
\_...
Mailing Lists
\_ Beginners
\_ General
\_ Hackers
\_ ODBC
\_ ...

and so on...

or one could provide options to narrow search results by specifying
parameters to the search, for example "select query url:documentation/8.2"
would return only results whose paths contain the provided url parameter and
whose pages contain the words "select" and "query"...

I think `information_schema' should be indexed as:

   - information
   - schema
   - information_schema

There is nothing wrong with indexing both.

that actually worked on the old one as well. The only new thing there is that you can now select a group (Eg dev lists)
andit will search in all lists in that group.

Maybe an 'advanced' link next to it? There should be room. Not likely there is room for both that and a dropdown of
sitesections though, so which is most important?
