Yeah if you put the tags in the content of the posts they will get indexed and search should find them, keep in mind the body of the posts are searched when you search in "posts" so if you are only searching for titles they wont show up.

@alff0x1f ok

I have a problem with the search. I have on my server two forums. my MongoDB has both networks. The search returns an error message in both.

@agusputra yeah its truly, but it can update only from console via npm i nodebb-plugin-dbsearch

@Kowlin Thanks, I appreciate your help!

Ignore this please. Seems to work now.

@terfex I don't think so... 2.8 just included a new command we take advantage of.

@Richa-Singh No

Thanks for reporting. Fixed in https://github.com/NodeBB/NodeBB/commit/9170ee831aefddc2ec4ddeff69098fb7ec6e07a4

If it isn't by default, it probably is if you make a plugin

I have upgraded to mongodb 2.6.4, I have run the following command to upgrade the mongodb to v5 mongos --configdb 127.0.0.1:27017 --upgrade with no error, I have clicked on reindex the database. when I search I get the following stuff in the cli MongoError: Unable to execute query: error processing query: ns=0.search limit=50 skip=0 Tree: $and key == "topic" TEXT : query=cool, language=, tag=NULL Sort: {} Proj: {} planner returned error: need exactly one text index for $text query at Object.toError (/nodebb/node_modules/mongodb/lib/mongodb/utils.js:114:11) at /nodebb/node_modules/mongodb/lib/mongodb/cursor.js:700:54 at Cursor.close (/nodebb/node_modules/mongodb/lib/mongodb/cursor.js:983:5) at commandHandler (/nodebb/node_modules/mongodb/lib/mongodb/cursor.js:700:21) at /nodebb/node_modules/mongodb/lib/mongodb/db.js:1847:9 at Server.Base._callHandler (/nodebb/node_modules/mongodb/lib/mongodb/connection/base.js:445:41) at /nodebb/node_modules/mongodb/lib/mongodb/connection/server.js:478:18 at MongoReply.parseBody (/nodebb/node_modules/mongodb/lib/mongodb/responses/mongo_reply.js:68:5) at null.<anonymous> (/nodebb/node_modules/mongodb/lib/mongodb/connection/server.js:436:20) at EventEmitter.emit (events.js:95:17)

@Ted @a_5mith Okay. I'm going to disable solr plugin then. Thank you guys for your help.

Can I select two tags and filter the discussions based on that?
