Alexandre,
How would the data type look like ?
Currently, this is what I have:
<fieldType name="days_of_year"
class="solr.SpatialRecursivePrefixTreeFieldType"
geo="false"
worldBounds="0 0 366 366"
distErrPct="0"
maxDistErr="0.00000009"
units="degrees"
/>
<field name="state" type="string" indexed="true" stored="true"
multiValued="true">
<field name="presentDays" type="days_of_year" indexed="true"
stored="true" multiValued="true"/>
<field name="absentDays" type="days_of_year" indexed="true" stored="true"
multiValued="true”/>
This is how I am indexing each record:
for-each student:
get the presence/absence period list
for each presence/absence period
get the state (either presence or absence) and add the value to
*state* field inside the doc
if the state is absence, add the absence period to the
*absentDays* field
if the state is presence, add the presence period to the
*presentDays* field
So, for student "X" (taken from my previous msg):
Student "X" was `absent` between dates:
Jan 1, 2015 and Jan 15, 2015
Feb 13, 2015 and Feb 16, 2015
March 19, 2015 and March 25, 2015
Also "X" was `present` between dates:
Jan 25, 2015 and Jan 30, 2015
Feb 1, 2015 and Feb 12, 2015
This is how I think my student record would look like. Does it look correct
?
{
id: "X",
state: ["absent", "present"]
presentDays: [ [01 15 366 366], [13, 16, 366, 366], [19, 25, 366, 366] ]
absentDays: [ [25, 30, 366, 366], [1, 12, 366, 366] ]
}
Also how would I represent the year in this case:
Student "Y" was absent between Jan 1, *2012* to Feb 1, *2015* ?
I would appreciate if you can provide an example of how to modify my
fieldType definition to store timestamp level granularity.
Thanks,
Sudheer
