+ * String index tries are prepaired structures used for fast greedy search of the string
+ * (index) by unique string prefix as key.
+ *
+ * Index tree build for two lists together can be explained in the following datagram
+ *
+ * Lists:
+ *
+ * {Januar Februar Maerz April Mai Juni Juli August September Oktober November Dezember}
+ * {Jnr Fbr Mrz Apr Mai Jni Jli Agt Spt Okt Nvb Dzb}
+ *
+ * Index-Tree:
+ *
+ * j 0 * ...
+ * anuar 1 *
+ * u 0 * a 0
+ * ni 6 * pril 4
+ * li 7 * ugust 8
+ * n 0 * gt 8
+ * r 1 * s 9
+ * i 6 * eptember 9
+ * li 7 * pt 9
+ * f 2 * oktober 10
+ * ebruar 2 * n 11
+ * br 2 * ovember 11
+ * m 0 * vb 11
+ * a 0 * d 12
+ * erz 3 * ezember 12
+ * i 5 * zb 12
+ * rz 3 *
+ * ...
+ *
+ * Thereby value 0 shows pure group items (corresponding ambigous matches).
+ * But the group may have a value if it contains only same values
+ * (see for example group "f" above).
+ *
+ * StrIdxTree's are very fast, so:
+ * build of above-mentioned tree takes about 10 microseconds.
+ * search of string index in this tree takes fewer as 0.1 microseconds.
