I have a complicated Find and Replace problem in WORD 2003 under WIN XP.

I have a word doocement that contains strings similar to the following:
*11(1) [5] [85] [97] [104] [149]; *29(2) [226]

I want to find all entries *11(1) followed by a string of references each
one enclosed in square brackets and the whole "element" terminated by a
semi-colon. Having found them, I want to replace those references which are
less than [145]. So in the example above, I want to end up with:
*11(1) [149]; *29(2) [226]

However if I wanted to remove all references less than, say, [150] then I
would want the result to be:
*29(2) [226]
i.e removing the complete entry including the 11(1) becasue it is now
redundant.

Is it feasible to do this using Find and Replace or must I resign myself to
doing it manually?

Many thanks in advance to anyone who can help.
