eZ Find fetch in one specific site id when installation is in multiple site environment

Friday 02 April 2010 8:38:35 am

Hi Matthieu,

When enabling 'SearchOtherInstallations', eZ Find will search the public indexed content of any other eZ Publish instance using the same Solr engine. This is not very granular though, as you say. The option of adding a raw request appendix is definitely one technical way of doing, waiting for eZ Find to allow for more configurability on this point. From the top of my head, your ezfind.ini override could look like this :

[SiteSettings]
SearchOtherInstallations=enabled

[SearchFilters]
RawFilterList[]='meta_installation_id_s:6277a18357e711cf13fd15dbef90ce0d'

where the last element of the raw filter is the ezfind_site_id, which you can get this way :

SELECT value FROM ezsite_data WHERE name='ezfind_site_id';

or using PHP :

$eZFindSiteId = eZSolr::installationID();

You can obviously 'OR' the different site as follows :

[SearchFilters]
RawFilterList[]='meta_installation_id_s:6277a18357e711cf13fd15dbef90ce0d OR meta_installation_id_s:1234a18357e711ccde5d15dbef90ce0d'

I was sure there was an issue reported for easing the control of which third-party eZ Publishi instance are searched in, but can't get a hold on it now. I may have dreamt a bit. You may want to report it !

Hope it helps,
Cheers !

Hope it helps!

After enabling

SearchOtherInstallations=enabled

You can also try to do it dynamically possibly searching across more than one, by passing the id's you want to search for in the'filter' parameter for the ezfind fetch function in templates:

 'meta_installation_id_s:(siteIDA OR siteIDB)'

You have to look up the side id's as Nicolas described above

Be aware if you use the RawFilterList, it will always be applied for that siteaccess (or globally if you specify it in the extension settings).

For the good understanding: all this only works if you have several sites using a common ezpublish DB

Hi Matthieu,

You are right about the REST part ... but:

1) the permissions implementation still needs DB calls to be made, so ez Find can construct a corresponding Solr filter query. If its not in the same DB (with sites basically having all a different root node), it will fail .. well even worse, it does not make sense in the general case.

2) the returned objects to the templates are actualy extended versions of eZ Publish objects, requring DB calls for every result displayed

Now, the use-case you mention is actually part of a larger family of use cases and its being addressed in the next development cycle.

To solve 1), we'll have to implement a system to interrogate "foreign" eZ Publish instances about what permissions to activate (a set of policies basically) in order to construct the right query filter. The very simple implementation we currently have is that "foreign data" is searched as long as it is flagged to be readable by anonymous users .... ok for some use-cases, but certainly not in general

To solve 2), I am working on extending eZ Find so it also optionally stores serialized versions of eZ Publish objects. Once that is done, no more DB calls are needed for that part (and a large speedup possible too, but that is another story)

So if I understand your situation correctly, with indexes to be searched from really foreign installations, you will have to resort to the rawSolrRequest fetch function. You will be able to use the stored values for urls and so, as well as the "plain text" versions of most of what is indexed from attributes, but not the rich content (like ezxml, ezselection, ezmatrix, images, ... and so on) in the display of the search results

I hope this clarifies the limitations we have today (but which will certainly be lifted in future versions)

Have a nice weekend

A little feedback about eZ Find rawSolrRequest fetch.

It works like a charm :) I have been able to request a foreign index very easily and luckily all the inforrmation I need is indexed.

Here is an example of a fetch for those we want to try :

{def $results = fetch(ezfind, rawSolrRequest, hash(
                                                    'baseURL', 'http://localhost:8983/solr',
                                                    'request','/select',                                                    
                                                    'parameters',hash('q','*:*',         
                                                                      'bq','meta_installation_id_s:54b480cf2df845e2606e2fe786d1eca9^1.5',
                                                    )))}
