Relevanssi and numbers.

What is your minimum word length setting in Relevanssi settings? Could it be six?

Minimum word length is 2.

Well, I have to say I don’t know, not without looking under the hood. Have you tried re-indexing the database and deactivating and reactivating the plugin?

Hey Mikko,

yes, ive tried both those things – its a strange occurance.

as far as im aware it worked flawlessly before i updated wordpress to 3.6 – but that was only in tests.

it was only brought to my attention when someone in the shop front tried using the website for a product that indeed we did sell but could not be located by its 5 digit reference :/

do you want any details for login? i remember that you looked at my site for woocommerce issues before.

i can confirm this number 26341 is in the postmeta table too. i have checked via phpmyadmin for this to make sure it is being saved correctly.

You can check the _relevanssi table as well – does the number appear there in the “term” column?

You can send me the logins to mikko @ mikkosaari.fi.

Hey Mikko,

there is no record of the 26341 word in the _relevanssi table.

Looks like there’s a bug in Relevanssi in how numeric search terms are handled. Next version will fix that.

Hi Mikko,

I’m facing exactly the same problem.
1-Do you have an update on the problem?
2-Do you need a hand?
3-Where should I look?

My bad, all is good.

Mikko, I love your plugin.

Same problem here, but then with version numbers. So searching for i.e. “WordPress+3.7” would ignore “3.7”. Especially on technical websites this is a problem.

Thanks for the great plugin! I love it.

I solved it in common.php

Replace

$a = preg_replace('/([[:punct:]])+/u', ' ', $a);

with

$a = preg_replace('/((?!(\.\d))[[:punct:]])+/u', ' ', $a);

This leaves numbers like “.55” and “3.7” in the index, while before they were changed to “55” and “3 7”

Hope this helps others too.

Changing the default function is a bad idea, as your changes will be then overwritten when Relevanssi is updated. Instead, make a copy of the relevanssi_remove_punct() function, call it something else (say vinx77_remove_punct()), make changes there and then add this:

remove_filter('relevanssi_remove_punctuation', 'relevanssi_remove_punct');
add_filter('relevanssi_remove_punctuation', 'vinx77_remove_punct');

This function is designed to be replaced with another function if necessary, so there’s no reason to change the function in common.php.

Thanks Mikko for the suggestion, as indeed I need to edit with every update. ?? I’d prefer if you could add an option for indexing numbers, of course.

Now got below code, but doesn’t work if I put it in my template’s functions.php – rebuilding the index doesn’t work (0 documents in the index). Where should I put it? Or what should I do different?

function relevanssi_remove_punct_not_numbers() {
	$a = strip_tags($a);
	$a = stripslashes($a);

	$a = str_replace("·", '', $a);
	$a = str_replace("…", '', $a);
	$a = str_replace("€", '', $a);
	$a = str_replace("­", '', $a);
	$a = str_replace(chr(194) . chr(160), ' ', $a);
	$a = str_replace(" ", ' ', $a);
	$a = str_replace('’', ' ', $a);
	$a = str_replace("'", ' ', $a);
	$a = str_replace("’", ' ', $a);
	$a = str_replace("‘", ' ', $a);
	$a = str_replace("”", ' ', $a);
	$a = str_replace("“", ' ', $a);
	$a = str_replace("?", ' ', $a);
	$a = str_replace("′", ' ', $a);
	$a = str_replace("—", ' ', $a);
	$a = str_replace("–", ' ', $a);
	$a = str_replace("×", ' ', $a);

        $a = preg_replace('/((?!(\.\d)):punct:)+/u', ' ', $a);
	//$a = preg_replace('/:punct:+/u', ' ', $a);
        $a = preg_replace('/:space:+/', ' ', $a);
	$a = trim($a);

        return $a;
}

if ( function_exists( 'relevanssi_remove_punct' ) ) {

	remove_filter('relevanssi_remove_punctuation', 'relevanssi_remove_punct');
	add_filter('relevanssi_remove_punctuation', 'relevanssi_remove_punct_not_numbers');

}

Your function is missing the argument, it should be

function relevanssi_remove_punct_not_numbers($a) {

Otherwise it seems correct to me.
