Configure multiple LINE_BREAKER strings?

I have line breaks signified by 2 different strings.

This works (keeping BK1 text as part of next event):

LINE_BREAKER = ([\r\n]+)(BK1)

This works (discarding BK2 text as part of breaker):

LINE_BREAKER = ([\r\n]+BK2)

But this does not work:

LINE_BREAKER = (?:([\r\n]+)(BK1))|(?:([\r\n]+BK2))

I assume this doesn't work because the 3 captures are taken as $1, $2 and $3 (and $3 is undefined as far as LINE_BREAKER REGEX goes) instead of as $1, $2v1, $2v2.

I find that dealing with LINE_BREAKER settings tends to get messy when often it's simpler and equally effective to achieve the same thing by configuring proper line merging settings instead. Have you investigated that option?

Using LINE_BREAKER if it is a valid option, is always the most efficient impact on the Indexer, so I always start there.

You can try:

LINE_BRAKER=([\r\n]+(?=BK1)|[\r\n]+BK2)

However this is subject to lookahead limitations: if I remember correctly this means you can not use +,? and * in BK1 (not sure about {n})

Give this a try:

LINE_BREAKER = ([\r\n]+BK2)|([\r\n]+)(?=BK1)

Hope this helps.

No worky; this completely ate the records starting with BK1 (for the same $1/$2/$3 reason/problem).
