Tag Handling #22

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
How will we implement tags? It seems to be quite difficult, and there are
few discussions about it online.

Here's how we probably should do it:
http://wiki.apache.org/solr/UserTagDesign

Does anyone understand that? (If you do, implement it :))

Perhaps some more info:

We are going to do this by storing the tags as separate documents in Solr. So, 
each
user will have a "Tag Document" for each venue she tags, containing fields such 
as:

taggedObjID, user/id, tags

Searching by tags will then contstruct queries to take these tag documents into 
account.

Ehm, I saw somewhere that you said we should decide whether the IDs are Strings 
or
integers, I think that it is easier to implement them as strings in solr.

We decided today that we wouldn't care about the special cases of simultaneous
updates, just getting an implementation that works. After all, this is a 
prototype.

I have modified a bit VenueModel to includes tags. If no tag is input, that's 
fine.
You can test it at http://localhost:8080/foodle-x9/tag/tagmodel_test.jsp and 
check in
Solr if it works.
Don't forget to copy schema.xml to solr/conf
I am using tag.EditController servlet to add the venue with the tags.

However, if we use it this way, I don't think that TagModel will be so useful. 
We can
use its static methods to retrieve the venues corresponding to the tag, or the 
tags
for a venue.
