Questions A

[BlackMage]

Hey Everyone,

So I have MongoLantern to be potentially used in 3 different sites to
implement in but I am having a few problems.

1. Searching Multiple Terms

In the chunks for an item, I have {'cat','bat', 'boat'}

When searching, if I pass in:

$search->setQuery('cat');

It works. But if I do :

$search->setQuery('cat dog');

It fails. So how can I search for possible multiple terms? Looking the
the code I noticed its tokenizing data.

2. Dictionary

Reviewing the code, I found a way of disabling the dictionary and
decided to add a constant as a way of turning the dictionary
synchronization on or not.

Also for the dictionary, batchInserts would speed up the process. The
figure .025 given per term is variable depending on a multitude of
factors.

Yes.

Try change matchmode to "ANY" and see whether it returns results for you.

Thanks

Code Example FOR MULTIPLE TERMS match

$search = new MongoLanternQuery();
$search->indexName = 'youindexname';
$search->Connect();

$keyword = 'cat dog';

$search->setQuery($keyword);

$search->setMatchMode('ANY');

$search->setSortMode('RANK');

$search->setIntelligentQueryMode(true);

$resultList = $search->Execute($limit);

Ok, here is what is weird.

$search->setQuery('cat dog');

works

$search->setQuery('Get the cat of the balcony');

$search->setQuery('dog cat');

[Sougata Pal.]

can you place following codeblock before $search->Execute() and get me the output.

$search->debug = true;

[Sougata Pal.]

Thanks a lot. Let me reproduce the issue and get back to you with the solution.

[BlackMage]

It seems strange the regex is outputting numbers if there are two
cases.

[BlackMage]

Ok, thanks

[BlackMage]

Right here is the cause of the problem:

if(false !== ($contentDate = strtotime($content))) { // check for
valid date+time

return (int) $contentDate;

[Sougata Pal.]

Yes.  I have already fixed the issue and launching the latest version as MongoLantern-0.6-rc0.1.  You can have it from sourceforge in few minutes.

[BlackMage]

Ok, it works now. You took out the line all together. How come is was
there to begin with?

[Sougata Pal.]

As there was error on that line which could be logically fatal so I removed. We will plan the conversion little more and put it there.


Thanks for your contribution. Please let me know if you require something else.

[BlackMage]

No thanks. The only thing tha I would comment about is the dictionary.
It's a large file that might be better suited if imported to mongo
through the command line. PHP way is really. I left mine run for an
hour and it only got to 10 megs.

[Sougata Pal.]

Yes. True.  We will still planning the dictionary feature more to have best performance.
