Special characters in double quotes

It’s up to how your database stores the characters. Relevanssi looks for the literal strings, ie. “bj?rn?ya”, but if your database for example has the oslash entity instead, Relevanssi won’t know to look for that.

Right now the only solution is to have the database use the actual characters, but I’ll look into checking if Relevanssi can perhaps do something about this.

Terve Mikko,

Carlos Eriksson here;

I’m looking more into this issue and this is the setup:

There are 6 posts that have an ACF custom field with Bj?rn?ya Project in the field. Additionally, the term Bj?rn?ya appears in 5 additional posts as part of the title.

Set Relevanssi to index visible fields. Default to AND. Disable OR fallback. Match on whole words.

When searching using the exact phrase, “Bj?rn?ya Project” it returns 0 results. I expect 6 results to return.

When searching using the exact phrase, ‘Bj?rn?ya Project’ it returns 8 results. I expect 6 results to return.

When searching using terms, Bj?rn?ya Project it returns 8 results. I expect 6 results to return (since I’ve disabled OR fallback)

When searching using term, Bj?rn?ya it returns 11 results. This is expected.

Example of how the data is stored in the DB:

INSERT INTOwp_relevanssi(doc,term,term_reverse,content,title,comment,tag,link,author,category,excerpt,taxonomy,customfield,mysqlcolumn,taxonomy_detail,customfield_detail,mysqlcolumn_detail,type,item`)
VALUES
(7260, ‘bj?rn?ya’, ‘ay?nr?jb’, 1, 1, 0, 0, 0, 0, 0, 0, 0, 2, 0, ”, ”, ”, ‘post’, 0);`

Have I set something up incorrectly, am I misunderstanding how the indexing works? I don’t understand why it returns 8 results.

Terveisin,
Carlos

Searching for 'bj?rn?ya project' or bj?rn?ya project is the same; the single quotes are removed and inconsequential. Do the two extra results for this search perhaps include the word “project” somewhere else in the post? That should be the case.

As for why the phrase doesn’t work, do check the wp_postmeta database: does the word “bj?rn?ya” appear in the post content like that, or with oslash entities? If the database has entities, that would explain why the phrase search doesn’t work.

Ah yes, that makes sense for the single-quoted search terms then.

It’s the phrase search that isn’t making sense to me at the moment.

I’ve checked the post_meta as well, this is one of the rows (though the data is stored the same way for all of them)

INSERT INTOwp_postmeta(meta_id,post_id,meta_key,meta_value`)
VALUES
(151635, 7260, ‘project_imported’, ‘Bj?rn?ya Project’);`

Hmm, not entities then. Can you please show me the MySQL query Relevanssi is doing for the search? Is the phrase query appearing correctly there, and is it targeting the right content?

The queries seem correct. What if you run just this SQL query?

SELECT ID
FROM wp_posts AS p, wp_postmeta AS m
WHERE p.ID = m.post_id
AND (m.meta_key NOT LIKE '\_%'
OR m.meta_key = '_relevanssi_pdf_content')
AND m.meta_value LIKE '%bj?rn?ya project%'
AND p.post_status IN ('publish','draft','private','pending','future','inherit')

Does this find the posts with the phrase in the custom field? If it does, then I’d start deconstructing the bigger MySQL query to see what part of it restricts the correct posts from the results.

I tested this query on my test site and it does work; if I put the phrase “bj?rn?ya project” in a custom field, this query does find the correct post.

Running this query returns 12 rows, all correct –- each post ID is returned twice because there are actually two custom fields that contain “bj?rn?ya project”

Ok, so the phrase matching is working. I’d start looking at the query components then:

SELECT COUNT(DISTINCT(relevanssi.doc))
FROM wp_relevanssi AS relevanssi
INNER JOIN wp_postmeta
ON ( relevanssi.doc = wp_postmeta.post_id )
WHERE relevanssi.term = 'project'
AND ( wp_postmeta.meta_key = 'date_published' )
AND ( relevanssi.doc IN (
SELECT DISTINCT(posts.ID)
FROM wp_posts AS posts
WHERE posts.post_type IN ('report') ) )
AND ( (relevanssi.doc IN (SELECT ID
FROM wp_posts
WHERE (post_content LIKE '%bj?rn?ya project%'
OR post_title LIKE '%bj?rn?ya project%' )
AND post_status IN ('publish','draft','private','pending','future','inherit'))
OR relevanssi.doc IN (SELECT ID
FROM wp_posts as p, wp_term_relationships as r, wp_term_taxonomy as s, wp_terms as t
WHERE r.term_taxonomy_id = s.term_taxonomy_id
AND s.term_id = t.term_id
AND p.ID = r.object_id
AND s.taxonomy IN ('post_tag','reference_type')
AND t.name LIKE '%bj?rn?ya project%'
AND p.post_status IN ('publish','draft','private','pending','future','inherit'))
OR relevanssi.doc IN (SELECT ID
FROM wp_posts AS p, wp_postmeta AS m
WHERE p.ID = m.post_id
AND (m.meta_key NOT LIKE '\_%'
OR m.meta_key = '_relevanssi_pdf_content')
AND m.meta_value LIKE '%bj?rn?ya project%'
AND p.post_status IN ('publish','draft','private','pending','future','inherit'))) )

Looking at this query, there are couple of restrictions here:

– The post must have the word “project” in the Relevanssi index. That should not be a problem.
– The post must have the custom field date_published – does it?
– The post must be of type report – is it?
– The post must have the phrase somewhere in it, and you’ve already confirmed that works as it should.

So there are essentially two parts where the query can fail to produce results.

I’ve manually verified each of the 6 entries I would expect to return for the term “Bj?rn?ya project”. Each post has a custom field date_published and is of the post_type report.

It hadn’t occurred to me to run this scenario before but I just tested the term “Bjornoya Project”, and this returns 6 results, mit? perkele? This result is the expected behaviour.

This, to me, suggests that there’s some encoding problem going on.

• This reply was modified 3 years, 7 months ago by fiinixdesign12.

Yes, that very much sounds like a database collation problem to me. What is the collation on the wp_relevanssi database table, what about wp_postmeta or wp_posts?

Encoding: UTF-8
Collation: utf8mb4_unicode_520_ci

for all tables

These are the default settings we use on 99% of projects (btw).

Those should work just fine.

On my test site the "bjornoya project" query returns results the same results as "bj?rn?ya project"?and "bj?rn?ya project", that’s the expected behaviour as that’s how the MySQL collation works. But why the correct form is not working, I’m pretty much running out of ideas here now…

Are you searching through the WP UI? All 3 variations return the same results when running a manual query to the DB but only “bjornoya project” returns results through the WP UI.

I appreciate your time and attention.

I’m searching with WP UI, and it works fine. This just should work. Can it be some third party that’s interfering? Another plugin? Something that somehow encodes the query in the middle?
