Searching for Spock with an O2 sensor

[NewArt]

I plead guilty to using unsearchable short forms when writing. While a discussion is being carried out on another thread concerning pointing to the search function, I find myself wondering if it is a requisite function of search functions to exclude 2 letter words such as «O2» in search keywords. Since in this country we rarely use the term lambda to describe an oxygen sensor, it is very difficult to do a search for threads pertaining to said topic since «sensor» and «wire» bring up more irrelevant threads than I care to plow through. Oh well...
