Empty result sets?

shawn · Feb 29, 2012

Anybody else having a problem with running a search query and getting zero results? If I search a second time for the same exact thing, it'll come back with 900 responses.

I'm guessing there's a timeout variable that needs to be a bit longer than it currently is...?

Does the server error log show anything up?

CTXMedia · Feb 29, 2012

I get three or four of those per day. I'll post my XF error log details later (I'm on the mobile ATM).

Cheers,
Shaun

Not when it happens, no. I do have a couple of the "No response from Elasticsearch" errors, but they weren't logged when this happened. I'm going to force IP/port for that stuff tonight.

shawn · Feb 29, 2012

I checked the elasticsearch port and IP information. I already had it forced to an IP and port in both the elasticsearch config and in XF, so I'm not sure why I'm getting the "No response" errors.

CTXMedia · Mar 1, 2012

Okay, well here's the report I get in the XF error log:

Code:

Always the same error - never the same search term - and other than a few of these a day it's working perfectly.

I have results set to 900 so that old posts appear in the search results, which slows it a little compared to the default 300 posts - but I don't think that's the issue.

Anyway, hope this helps if we're both experiencing the same thing?

Cheers,
Shaun

It almost seems that if a search as not been done for a while the ES/Java client goes to idle, and the first search wakes it up, but in the proccess it returns no result for that first search.

Possibly set up a shell script to run every few minutes just calling back to ES via curl to keep it alive and see if that helps?

shawn · Mar 1, 2012

Slavik, what would the script need to say?

Here's my error:

Code:

#!/bin/bash
curl http://127.0.0.1:9200

Set it to run on cron every minute or so...

Nice one. Thanks. I'll give that a go and report back next week.

shawn · Mar 4, 2012

I added the cron to run every other minute. Forgot to send its output to null for the first couple of hours. :lol:

Problem is, now I'm getting 10-20 of the Elasticsearch server returned no response errors per day.

How parculiar

Maybe change the script to pass it an actual search query?

curl http://127.0.0.1:9200/your_xs_index_name/_search?q=hello

shawn · Mar 5, 2012

Nope. I changed the cron to run an actual query. Set it to run every 120s. Had two errors in the last ~35mins.

Hmm...

[edit]: Trying something slightly different. I'll keep you posted.

shawn · Mar 6, 2012

Ok... definitely no better:

Code:

Elasticsearch server returned no response. Is it running?  Today at 5:42 PM - library/XenES/Search/SourceHandler/ElasticSearch.php:721

Elasticsearch server returned no response. Is it running?  Today at 5:41 PM - library/XenES/Search/SourceHandler/ElasticSearch.php:721

Elasticsearch server returned no response. Is it running?  Today at 3:15 PM - library/XenES/Search/SourceHandler/ElasticSearch.php:721

Slavik · Mar 6, 2012

Hmm, some deeper investigation may be required, though this may be something beyond my skillset.

shawn · Mar 7, 2012

Slavik said:
curl http://127.0.0.1:9200/your_xs_index_name/_search?q=hello

If I run a query like that from the command line, I get the following response:

{"error":"IndexMissingException[[cluster_1] missing]","status":404}

Also, I'm finding that most searches die the first time they're ran. If you run them again immediately afterward, they go through just fine.

I'm finding that the elasticsearch 'manual' is contradictory. A lot of it is out of date. None of it is particularly in-depth. For example, older pages talk about setting memory limits the way that Slavik described in his write-up. Newer manual pages say *not* to do it this way. The latest stable build (0.19) doesn't even include the elasticsearch.conf file where these variables were defined.

shawn · Mar 7, 2012

Also getting this error now when I try to reindex:

Undefined variable: indexName

I have to manually delete the index directory from the command line first.

I've increased a timeout variable related to ES, though it was set to 10 seconds before which should be plenty. (It's 20 seconds now.)

You may want to look at changing your memory configuration options for ES if it's happening consistently.

Hey Mike,

The times i've been able to generate the error it comes back after 4-5 seconds with no result, definately not as high as 10 seconds for me at least, and the memory settings I have configured should most definately not be an issue (Es has 4gb available to it)

Empty result sets?
