Its unlikely that the index "degrades".

For your first part of the posting, yes you will need to escape the wild card characters.

For the second part of your problem you are token matching when searching for your long strings in the text, not doing numeric comparisons. The tokeniser is probably returning the same token for your similar but not identical numbers which is why a match is reported. The solution is to compare the numbers numerically rather than textually. If you can get your number into a property it may be a good start.

No, wait.
What I meant when saying "escape wildcards" was that in order to use wildcard characters as wildcards (not as the character itself), i needed to escape them.
For example, if I wanted to search for all the users whose email started with "mymail" I had to write
@cm\:email:mymail\*
but it should be
@cm\:email:mymail*
First it worked as in the first example, but now, after a full indexing it works as the second example. This is how lucene searchs are supposed to work, isn't it?.
