Adds conversation search, with options to search by recipient

Users must be a member of the conversation to see the conversation in search results.

Does not permit moderators/administrators to see another person's conversations in search results.

Adds each conversation, and conversation message to the XenForo Search store (MySQL or Elastic Search), which may result in a larger search index.

New Conversation Permissions

Just takes away a user's "reply" button, no banners.

The reply limit is for the entire conversation, but the limit is per user group. Consider when User A & User B are members of a conversation.

User A can have a reply limit of 5. User B can have a reply limit of 10.

Once the conversation has >5 replies, User A can no longer post. Once the conversation has >10 replies, User A and User B can no longer post

Conversation Message Edit History

Adds edit history for conversation messages.

Conversation Title Edit History

Adds edit history for conversation's title, and implements a new moderator permission "Manage Conversations by anyone" to allow non-conversation starters to edit a conversation.

Allow conversations with no-one

A global option to allow users to send conversations to just themselves.

Known Issues

• Edit History does not respect/implement any silent editing window.
• This add-on likely will require a higher memory limit (ie <256mb isn't going to cut it) due to extra search results.

Installing for large forums

For large forums, please try manually adding all the columns in a single step.
This took upto 5 minutes for 1.3 million conversation messages (compressed).

SQL:
ALTER TABLE `xf_conversation_message`
ADD COLUMN `edit_count` int unsigned not null default 0,
ADD COLUMN `last_edit_date` int unsigned not null default 0,
ADD COLUMN `last_edit_user_id` int unsigned not null default 0;
ALTER TABLE `xf_conversation_master`
ADD COLUMN `edit_count` int unsigned not null default 0,
ADD COLUMN `last_edit_date` int unsigned not null default 0,
ADD COLUMN `last_edit_user_id` int unsigned not null default 0;
Permissions

• Can Reply to Conversation. - Default - If a group can start a conversation, they can reply.
• Reply Limit for Conversation. - Default - If a group can start a conversation, the reply limit is disabled (ie infinite).
• Manage Conversations by anyone. - Default - If a group can edit any conversation posts, this permission is set for them.

Manual post-installation steps - Rebuild Search Index

The add-on will report (via server errors) if conversation related content types require re-indexing.

Performance impact

• 1 extra query per conversation message posted due to indexing, and indexing itself.
