Google drive link not working. It's saying "You need access". You have to share a public link.

I have made the Google Drive Link Shareable 

This is again your 3rd party plugin issue and not elgg. Contact the owner of the plugin.

3.3

1 - Check how you placed these plugins. The start.php should be in:

/mod/plugin_name/start.php

2 - Check the read/write rights permissions on these uploaded plugins' directories/files.

3 - As always, try use search before creating a new discussion.

Are you definitely sure that you have Elgg version 3.3 installed? Could it be that you have installed Elgg 2.3 instead?

Before Elgg 3 a start.php file was required. Now it could have happened that you unzipped the plugin archive within a subfolder of the plugin folder inside the mod directory (i.e. you would have mod/plugin_name/plugin_name/start.php instead of mod/plugin_name/start.php). Or there was a permission issue with the unzipped files preventing the webserver from accessing/reading these files (i.e. there files seems non-existing to the webserver even when being there).

With Elgg 3 the plugins no longer need to have the start.php file in all cases. For the time being they still can have a start.php. Alternatively, they can have a ootstrap class containing the init function. Or if a plugin doesn't require an init function the plugin won't need a start.php or bootstrap class at all.

The start.php file not being present in a plugin compatible with Elgg 3 should be no problem. But if you try a plugin without start.php written for Elgg 3 on Elgg 2 it will result in the error message about the missing start.php file. But even with the start.php file re-added the plugin won't work on Elgg 2 as it was released for Elgg 3!

So, make sure you really have Elgg 3.3 installed. Make sure you use the plugin versions compatible with your Elgg version (may it be Elgg 2 or 3). And make sure the permissions assigned to the files and folders of the plugin and the owner:group the plugin files/folder belong to are correct.

Isn't that a similar (the same?) kind of query as given as an example at http://learn.elgg.org/en/stable/guides/search.html#custom-search-types for implementing a custom search? The example has been updated for Elgg 3 already and seems to include an order_by clause, too.

Amazing iionly. I missed that totally.. Thanks a lot for the help. 

Just one more question, will there be any performance benefit my moving geodata search alone to a custom table? 

Along with geodata, I am using some "metadata_name_value_pairs" for additional filters. But because of the complexity of geodata search, I moved geosearch to a separate table.

Just concerned about performance now.
