Use layer. Search to quickly query Elements

Search for elements in Mapx and use layer. Search;
Layer. Search supports query using comparison expressions. However, it often reports that the variable does not exist. The reason is that it requires the support of dataset. However, layer. datasets. Count and map. datasets. Count are both 0. Add layers.Code
Set DS = Main. map1.datasets. Add (midatasetlayer, lyr)
After adding the parameter, You can query it.

Problem:
Variable comparison expression. Single quotes are not supported. You can use "Or CHR (34) instead of double quotes.
Even more troublesome, Fuzzy Matching is not supported. No way. This is fast.

I had to write two searches, one being fuzzy match, one being compared by one element, and the other being slower. However, fuzzy match is not supported.
