"When a PC gets in touch with a contact, make a Connection + Connection test for the contact. The results of this test will determine how many ranks of information the contact knows about the question. (Apply die modifiers to this test based upon relevance of the contact to the subject
matter.) A PC then makes a test of Charisma + Etiquette + Loyalty rating. The contact will reveal that many levels of information about that topic for free. (Up to the number of hits scored by the contact for that topic.) If the contact knows more, additional information will require a payment to the contact of 50Â¥ * TR."
Connection + Connection = 12 dice for the contact. That is what gives you info on the subject. Thats on average, 4 hits.
PC makes charisma + etiquette + loyalty (as long as this is at least 12, they should typically get whatever the contact knows for free).
Thats it. In fact, the first test doesn't even have a timeframe listed for it, its instant, as its to find out what the contact already knows about it. So, up to threshold 4 information with a quick phonecall. They haven't asked around at all, thats the laster test (which has a 20 minute interval, not one hour), and there is not any risk with it. I'm not sure why you think there is.
This is in comparison to data search, which, going through the missions, the first 2 do not have listed as an option, and you MUST go through contacts to get the info. Something you also forgot, is that data search standardly has thresholds of 4, 8, 12, and 16 for the test. So, a 12 dice connections contact checking for info will on average get 4 hits. Your 12 die data search test, will get 1.
The first and second missions omit data search entirely as an option to get the information with.
The third mission specifically states what information is available via data search.
The fourth mission states exactly what charts you can use data search for, and lists the thresholds for each hit (some 4, some

as well as listing the interval as being 15 minutes. It also states which kinds of contacts are appropriate for each chart. Kudos from me to the writers on this one, thats how it should be done.
The fifth mission, like the first two, omits data search from the options to get info from the legwork charts.
The sixth like the fifth, omits data search.
As does the seventh.
Finally, the eighth is the first one to explicitly allow data search for all of the charts, but limits the rolls they can make to their skill in data search. Also changes it so that every 4 hits on data search equates down to 1 hit on the charts (following the standard data search thresholds).
Mission nine follows eights lead.
Ten follows eight and nine.
Elevent follows ten, nine, and eight.
So does twelve.
And thirteen.
And fourteen.
And fifteen. Though it also scatters about results for data searches for various parts of the story as well.
Sixteen has no legwork section at all.
Seventeen follows fourteen and the rest.
Eighteen has no legwork section either.
Nineteen follows seventeen and the others.
Twenty follows fifteen in that it also has various data search results scattered through it.
As does twenty-one.
And twenty-two.
And twenty-three.
Twenty-four follows nineteen and the rest.
And twenty-five.
So, that makes 5 that don't allow any search at all. (1, 2, 5, 6, 7)
2 that actually spell out exactly what you can search for. (3, 4)
11 that allow it, but limit rolls to skill and use the normal data search thresholds.(8, 9, 10, 11, 12, 13, 14, 17, 19, 24, 25)
5 more that allow it, limit it as above, but also have explicit results scattered throughout for data searches.(15, 20, 21, 22, 23)
And 2 with no legwork section at all.(16, 18)
