Global Search by IP Address
Global search treats each period character as a space, so searching for an IP address splits it into four keywords. This means you may get results with the same numbers in different orders, because keyword order is not relevant. For example, searching for 111.222.333.444 could return both 111.222.333.444 and 111.222.444.333.
By default, global search uses starts-with matching for keywords. You can enclose any keyword in quotation marks to turn this off, as described in Tips for Effective Global Searches. Global search does not support the enclosing of multiple separate keywords in quotations to express order.
