Full text search on substring in PostgreSQL -


i trying retrieve data database using to_tsquery() on basis of text search. able results complete word search not substring.

example:

select * snp_gene_context protein_name @@ to_tsquery('english','kin') , gene_dist='0';

i able rows containing word 'kin11' unable rows containing 'kinase'.

full text search doesn't work on substrings — words.

for indexed substring searches you'd need use pg_trgm extension. there's good article faster like/ilike searches using pg_trgm on select * depesz blog. there's trade-of though — slower writes.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
