The fastest, easiest way to retrieve your records.
TSearcher is a component which gives its best performances in
client/server applications, where limit the amount of data to that ones
which are really necessary is a must. For that reason i've not
exploited the dataset filtering instructions, as these instructions, in
particular cases, bring the whole data cursor in your local memory and
only here they apply the filter. Viceversa, TSearcher filters the data
only at server level. Tsearcher builds a SQL statement with some
search criteria that user sets; the used SQL is based on SQL97.
