Multiple warnings/errors on search results page

Please file a second support request for the question in #1, and check that your content is fully indexed and that you're indexing whatever creates the page about tutoring. Thanks.

I'm having exactly the same issue

I'm unable to duplicate. In a new minimal drupal install I used the default fuzzysearch index and server. I generated 50 nodes with devel generate. I created a search_api page for searching. I'm using the current dev of fuzzy search and search_api 1.0. I'm using all the default settings. I did have to save the index fields settings as is in the default for an unrelated bug.

Any chance you can start with a fresh install and try it?

When generating the search excerpt for each matched entity, fuzzysearch reruns a clone of the search query to check for ngrams in that particular entity. From the looks of your errors, it appears that the excerpt query on line 209 isn't returning what is expected.

A search for the word apto created a $clean_grams array like this http://gyazo.com/1fa937a297cd605d62e5319d330400a0

If you could see what you have in your $clean_grams array that may help. Thanks.

After receiving these errors on one of my sites, I went to work trying to replicate the issue. After messing around for an hour, I think I finally got it.

1. Standard Core Install
2. Install latest Dev of Fuzzy Search, Search API 1.0 and Search API Pages 1.0-beta2
3. Go to /admin/config/search/search_api/index/default_fuzzysearch_index/workflow
4. Enable Bundle Filter
5. checkoff 'All but those from one of the selected bundles' and select basic page
6. Enable "node access'
7. The following the recommendation of http://drupal.org/node/1414138#comment-5547094 (which is mentioned by awolfy in http://drupal.org/node/1479566#comment-5809246 as a workaround)

I was able to trick the system by doing the following:

1. First enable the node access data alteration
2. switch to the fields config page and uncheck the "Node access information" field + Save
3. recheck the field and save again

8. Create a Search page
9. Generate some content with Devel
10. Re-index
11. Run a search

It appears once this has been done, you can't back out of it. (i.e. can't just remove the 'node access' and 'bundle filter' and reindex. It still throws up these errors.

I hope this helps you to replicate this awolfy. Let me know if you still can't replicate the issue

Got the same issue with Dev of Fuzzy Search, Search API 1.0 and Search API Pages 1.0-beta2

I got the same issue with Dev of Fuzzy Search, Search API 1.0 and using Views for a Site-Search-Page. The Errors appear only if I search for a part of a word. The search gives me a result (sometimes with text extraction sometimes only the title of the text) and these errors appear:

Notice: Undefined variable: clean_grams in fuzzysearch_build_excerpt() (Zeile 221 von /is/htdocs/wp11011745_D6ORBK4BRJ/www/.adm-tube.de/sites/all/modules/fuzzysearch/fuzzysearch.module).

As I understand it, the variable $clean_grams is there to store fetched ngrams from the database based on the user input.

In case the search is able to indetify some ngrams in the dabatase, it populates the variable (array in this case).
If there is nothing found, however, the variable is not populated, in fact it is not declared at all.

What fixed the issue for me was simply declarating it.
In the function "fuzzysearch_build_excerpt" declare the variable with "$clean_grams = array();". That did the trick for me.

thanks for the patch. Fixed the problem for me

#9 fixed it for me too

#9 works for me also

open file

modules/fuzzysearch/includes/service.inc

find lines 656/657:

// See @todo below
$results['result count'] = $count_query->execute()->fetchField();

overwrite with:

//------start of cheap fix------
//search used to crash on 1 and 2 character searches
if ( (@strlen($keys) > 2) )
{ $results['result count'] = $count_query->execute()->fetchField(); }
else
{ $results['result count'] = @$results['result count']; }
//------end of cheap fix------

a dirty fix, but does the job

Committed patch from #9. Thanks kunago and everyone!
