Non-Alphanumeric Characters

By default, non-alphanumeric characters in a

partialfields

query separate the query terms in the

same way as space characters. Generally use spaces as separators even when the original content used

different content as a separator. For example if you were trying to do a

partialfields

query for the

following meta tag:

You should use queries like:

partialfields=part:aaa%20bbb

partialfields=part:bbb%20ccc

The following non-alphanumeric characters are exceptions:

Character Description

Decimal point (.) A double URL-encoded (see “Appendix B: URL Encoding” on page 107) decimal

point can act as a decimal point in a number (for example, 250.01). For example

to query for a meta tag like:

Use a

partialfields

query like:

partialfields=number:1%252E1222

When a meta tag contains a decimal point with no numbers use the space as a

separator as previously mentioned. For example for a meta tag like this:

Use a

partialfields

query like (%2520 is a double URL-encoded space

character):

partialfields=pet:dancing%2520parrot

If a meta tag contains a number that has letters immediately before or after it, a

space should be used as a separator. For example, in the meta tag:

Use a

partialfields

query like:

partialfields=serialnumber:A1%202

1 2 ... 41 42 43 44 45 46 47 48 49 50 51 ... 115 116
