See this past topic in “About BOB” which explains why version numbers don’t get included in the search.
Also, see this reply in the sticky “About BOB” topic “How do I Search BOB?”, which explains that certains “stop words” are also excluded from searches. Java is not on the list, but some BusinessObjects-specific words such as WebIntelligence, Universe, Designer and so forth, are.
