Search for numbers, codes and references

How it works

In a query, Gmail separates two numbers with a space or a dash, and treats a dot as a decimal point. Google gives the example 01.2047-100, read as two numbers: 01.2047 and 100.

Examples

• 01.2047-100Open in Gmail ↗

  Read as 01.2047 then 100, not as a single reference.

What it does well

• Knowing this rule helps explain why a reference or invoice number doesn't always turn up as expected.

What it does badly

• A number containing dashes or dots (a reference, a formatted number) is split into several numbers, not read as a single value.Documented by Google · Gmail Help: search operators
