The software really isn't intended to be used this way. It would
be simpler to conjoin a number of searches. Assuming an interface
like
numberofmatches = regexp(pattern,string)
you can do something like
regexp("[Ii]",string)==1
&& regexp("[Nn]",string)==2
&& regexp("[Tt]",string)==1
&& regexp("[Uu]",string)==1
&& regexp("[Oo]",string)==1
Some interfaces also allow a flag to ignore character case.
regexpnocase("i",string)==1
&& regexpnocase("n",string)==2
&& regexpnocase("t",string)==1
&& regexpnocase("u",string)==1
&& regexpnocase("o",string)==1
To do this in a single RE, you have to use all 120 permutations,
[^IiNnTtUuOoNn]*[Ii][^IiNnTtUuOoNn]*[Nn][^IiNnTtUuOoNn]*[Tt]...
|[^IiNnTtUuOoNn]*[Ii][^IiNnTtUuOoNn]*[Uo][^IiNnTtUuOoNn]*[Nn]...
|...
