eHive uses a text search processor called Lucene. This supports a variety of wildcard and range search options which can help to do searches such as object number ranges.
Here's a couple of examples.
1. If your object numbers are simple sequences, you can just to '?' wildcard, which indicates one character.
So, searching on:
will find all object numbers with exactly four digits, with the first digit being a 5.
2. If you object number are always the same length (e.g. padded with zeros), then you can use the range option.
object_number:[1999.001 TO 1999.300]
will find all of the objects between these two numbers (the TO must be in upper case).
Note: Lucene is using purely alphabetic searching. If your object numbers vary in length, then you may not get the results you expect. e.g. object_number:[1999.1 TO 1999.300]
will include object number 1999.2000, as in pure alphabetical order, this comes between 1999.1... and 1999.3...
The next upgrade (Oct 2010) includes automated storing of a padded version of the object number you have entered. This is used in a new option to sort results by object number (part of the same upgrade), but will also allow us in the future to support more complex object number range searches.
