You can use regular expressions or operators in the SPARQL queries to filter the search.
Tutorials on how to code SPARQL queries are available on Internet but here is a reminder of the main regular expressions.
Option | Description |
---|---|
AR | The sequence contains AR |
^S | The sequence begins with S |
O$ | The sequence ends with O |
D* | The sequence contains zero or more occurrences of D |
M? | The sequence contains zero or one occurrence of M |
m.*r | The sequence contains M followed by any character and R |
m.*r, i | The sequence contains M followed by R ignoring case |
You can also use the following operators to express your query:
Operator | Function |
---|---|
A && B | A and B |
A UNION B | A or B |
A=1 | A is equal to 1 |
A != 5 | A is different from 5 |
A < 10 | A is less than 10 |
A > 50 | A is greater than 50 |
A <= 100 | A is less than or equal to 100 |
A >= 500 | A is greater than or equal to 500 |
A >= 5 && A <= 10 | A is 5 - 10 |
