Phrase queries and slop and positionIncrementGap ;)
The fieldType has a positionIncrementGap. This is the token delta
between the end token of one entry and the beginning of the next.
so the first entry: IFREMER, Ctr Brest, DRO Geosci Marines, F-29280
Plouzane, France
IFREMER would have a position of 1 and France would have a position of 9 or so.
If the positionIncrementGap was 100 then this entry:
Univ Lisbon, Ctr Geofis, P-1269102 Lisbon, Portugal.
Univ would have a position of 110.
Now if I seach "IFREMER France"~99 it'd match the first one
but searching "IFREMER Lisbon"~99 it would not match since the
positions are > 99 apart.
So you configure the positionIncrementGap to be greater than the
longest number of tokens you ever expect to have in a single entry.
