Ryan McKinley updated SOLR-2444:
--------------------------------
Summary: Update fl syntax to support: pseudo fields, AS, transformers, and
wildcards (was: support wildcards in fl parameter, improve DocTransformer
parsing)
I just started a new branch and implemented some of the things we have
suggested. Check:
https://svn.apache.org/repos/asf/lucene/dev/branches/pseudo/
This implements:
h3. SQL style AS
{code}
?fl=id,field AS display
{code}
will display 'field' with the name 'display'
h3. Pseudo Fields
You can define pseudo fields with ?hl.pseudo=key:value
Any key that matches something in the fl param gets replaced with value. For
example:
{code}
?fl=id,price&fl.pseudo=price:real_price_field
{code}
is the same as
{code}
?fl=id,real_price_field AS price
{code}
h3. Transformer Syntax [name]
The previous underscore syntax is replaced with brackets.
{code}
?fl=id,[value:10] AS 10
{code}
Hopefully this will make it more clear that it is calling a function.
