searching is not functional at all

I have installed Postbox about one month ago. And yes, I have indexed all folders. The Inbox folder is set to be available offline and I am using Mobile Me. I know it is difficult to solve this kind of problem. I just wanted to know if there is some known reason when this could happen.

I have the same problem. I am: WIN7, 4 Accounts, all IMAP. I've been running POSTBOX for 3 months, flawlessly, super fast search, now it's stopped running. I purchased a license hoping that would fix the problem, but search is still non-functional...
Every search turns up no results.
It seemed to coincide with the option to search by field, an option I hadn;t seen before, but perhaps it was always there.
Any search, in any field, always results in zero results now.

I am having the EXACT problem as Jeff, the only search that works for me is right clicking on an account. I cannot use Searching from menu Edit > Find > Advanced Search is functional as El Rizo can, it doesn't work.

I have been using Postbox for months, and never had this problem until the past couple of weeks. I starting using Postbox for my work email because it USED to be quicker to find emails/attachments than Mac Mail, but now that i cant easily search, i'm starting to regret shelling out $40

Nothing in the "Errors" tab in the Error Console, but in "Messages" i get this (i searched for "6176"):

FTIAlert: searchStmt.executeStep failed unexpectedly, boundQueryString = SELECT message_id, folder.uri, NULL, message_text.body, message.frecency, "0.0", NULL FROM message JOIN folder ON message.folder_id = folder.rowid JOIN message_text ON message.rowid = message_text.docid WHERE message.folder_id > -1 AND message_text match '"6176"' ORDER BY message.frecency DESC ex = [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [mozIStorageStatement.executeStep]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: file:///Applications/Postbox.app/Contents/MacOS/components/nsMsgFullTextIndexer.js :: anonymous :: line 749" data: no]

I get this:
