I posted this to the solr-user and got no love. I’m hoping somebody here might
be able to help me.
I’m using solr 6.5.0, which is fantastic, and I’ve come across an issue with
the collations in the spellcheck response.
The way the json is structured collations is an object with each collation
named ‘collation’ where it should be an array with multiple ‘collation’ object
elements. I’m using the ajax solr javascript library and because of the above
each successive collation object writes over the previous, leaving the last and
least likely collation.
I dug a little deeper and I noticed what I think is an error in
org.apache.solr.handler.component.SpellCheckComponent.java. The collationList
is a SimpleOrderedMap which requires a unique key for each entry to work
correctly. But, each collation is added with the key “collation”. As I see it,
there are two possible solutions:
1. Change the collationsList type to an ArrayList and ignore the key, or
2. Append a numeric value to the key so they become “collation0”,
“collation1”, etc
I’d just like to know I’m not going nuts and the issue really exists.
Below is the snippet of response json relevant to this issue, notice collations
contains multiple collation objects using the same key (collation):
"collations":{
"collation":{
"collationQuery":"haemorrhagic broken",
"hits":36,
"misspellingsAndCorrections":[
"hemorrhagic","haemorrhagic",
"braken","broken"]},
"collation":{
"collationQuery":"haemorrhagic brake",
"hits":22,
"misspellingsAndCorrections":[
"hemorrhagic","haemorrhagic",
"braken","brake"]},
"collation":{
"collationQuery":"hemorrhage broken",
"hits":16,
"misspellingsAndCorrections":[
"hemorrhagic","hemorrhage",
"braken","broken"]},
"collation":{
"collationQuery":"haemorrhagic braces",
"hits":23,
"misspellingsAndCorrections":[
"hemorrhagic","haemorrhagic",
"braken","braces"]},
"collation":{
"collationQuery":"hemorrhage brake",
"hits":2,
"misspellingsAndCorrections":[
"hemorrhagic","hemorrhage",
"braken","brake"]}
}
}
I’d appreciate any pointers with this.
Z.
