[jira] Created: (SOLR-966) Enhance the map() function to take in
multiple tuples
Enhance the map() function to take in multiple tuples
-----------------------------------------------------
Key: SOLR-966
URL: https://issues.apache.org/jira/browse/SOLR-966
Project: Solr
Issue Type: Improvement
Reporter: Noble Paul
Fix For: 1.4
The map function currently takes in only one min,max target. This makes it impossible to map it to multiple values .
It should be possible to pass on multiple sets of values
example
{code}
map(x,0,0,10,1,1,20,2,2,50)
{code}
it should allow an n number of float values (where n%3 = 0)

Noble Paul updated SOLR-966:
----------------------------
Attachment: SOLR-966.patch
decided to go w/ shalin's suggestion . added just a default value. The last value is optional. if not present ,the field value is used as default.

[jira] Commented: (SOLR-966) Enhance the map() function to take in

Noble Paul commented on SOLR-966:
---------------------------------
bq.However, both these approaches are mutually exclusive.
It is still possible to have both these working together.
For the no:of arguments 'n' if (n%3) == 0 then no default is used. if ((n%3)-1) =0 , then the last value can be used as default. Although it is more complex (to explain) it hopefully will meet most of the requirements of a switch - case - default
Thoughts?

[jira] Updated: (SOLR-966) Enhance the map() function to take in a
default value
Posted by "Shalin Shekhar Mangar (JIRA)" <ji...@apache.org>.

Shalin Shekhar Mangar updated SOLR-966:
---------------------------------------
Description:
The map function currently takes in only one min,max target and returns the field's value if it is not between min and max. This makes it very difficult to use it for scoring.
This issue aims to add an optional fifth parameter to the map function query which will be a default value that is used if the field's value does not fall between min and max. If this parameter is not specified, the behavior is the same as before for back-compatibility.

Shalin Shekhar Mangar commented on SOLR-966:
--------------------------------------------
I'm using the map function (FunctionQuery).
Consider the following (hypothetical) use-case:
I want to boost up listings of a certain category over listings of another category. Say for example, "SUV" and "Sedan". For each category, I've indexed a integer field, say "SUV" = 1 and "Sedan" = 2. Now I'm trying to boost SUVs over Sedans through function queries. This is just one of the many different boosts I need to apply.
So I use q=_val_:map(category, 1, 1, 3) _val_:map(category, 2, 2, 1). The priorities of the categories are not fixed i.e. they change at runtime. I cannot use a sort because of the many different boosting criteria I have. I cannot use the normal boosts because I don't want TF/IDF influencing the scores.
I hope the description makes sense.

Shalin Shekhar Mangar commented on SOLR-966:
--------------------------------------------
I guess the problem (feature?) of map is that if the field value is not between min and max, it outputs the value of the field. That makes it difficult to use map for scoring on numeric field values.
An alternative to Noble's approach can be to add an optional fifth argument for a default value. If value does not fall between min and max, map can output the default value. However, both these approaches are mutually exclusive.

Shalin Shekhar Mangar updated SOLR-966:
---------------------------------------
Attachment: SOLR-966.patch
Changed equals and hashcode method to take the default value into consideration.
I found a bug in the hashcode function:
{code}Float.floatToIntBits(min);{code}
which should have been
{code}h += Float.floatToIntBits(min);{code}
Since my knowledge of hashing is limited, it would be nice if someone can review this.
