1 How does exact match work?
2
3 Well, it's quite stupid because swish-e doesn't allow you to make exact
4 match to words. So, work-around is to add 'xxbxx' word at beginning of
5 string and 'xxexx' word at end (think of it as xxb(egin)xx and xxe(nd)xxx)
6 and then search for phrase (words in particular order).
7
8 So, title "human" will be indexed as "xxbxx human xxexx" if you want full
9 exact match. Then you can search it using (numbers are parameters to e[nr]
10 field in html forms):
11
12 1: exact match from beginning "xxbxx human"
13 2: exact match from end "human xxexx" (not really useful)
14 3: exact match begin and end "xxbxx human xxexx"
15
16 add 4 to those values (numbers are really bit-masks :-) to produce wild-card
17 match:
18
19 5: exact from beginning with wild-card "xxbxx human*"
20 6: exact from end with wild-card "human* xxexx"
21 7: exact begin+end with wild-card "xxbxx human* xxexx"
22
23 So, to define field which have to be searched using exact match with wild-card
24 on TitleAndResponsibility, you would use:
25
26 <input type="hidden" name="f1" value="TitleAndResponsiblity">
27 <input type="text" name="v1">
28 <input type="hidden" name="e1" value="5">
