Fuzzy matching with 

Hi all, 
  I’ve followed the tutorial on how to set up the SolrTextTagger [1] using biomedical ontology instead of the geotag. 

I can send a request and get a response that capture all the exact terms: 

curl -X POST   'http://localhost:8983/solr/bao_ontology/tag?overlaps=NO_SUB&tagsLimit=5000&fl=id,name,label&wt=json&indent=on&ignoreStopwords=true'   -H 'Content-Type:text/plain' -d 'We are testing a malignant ependymoblastoma and a very interesting Bachem'
{
  "responseHeader":{
    "status":0,
    "QTime":0},
  "tagsCount":4,
  "tags":[[
[…]
  "response":{"numFound":3,"start":0,"numFoundExact":true,"docs":[
      {
        "label":["BAO_BIO_RB_syn"],
        "name":["Å"],
        "id":"http://purl.obolibrary.org/obo/UO_0000019"},
      {
        "label":["BAO_BIO_RB_term"],
        "name":["ependymoblastoma"],
        "id":"http://purl.obolibrary.org/obo/DOID_4794"},
      {
        "label":["BAO_BIO_RB_term"],
        "name":["Bachem"],
        "id":"http://www.bioassayontology.org/bao#BAO_0000858"}]
  }}

And I was wondering whether it was possible to use fuzzy matching instead of strict matching. From the documentation doesn’t seems that the API offers more options than [2], but maybe programmatically? 

Any idea is welcome. 

Thank you in advance 
Luca

Hi Luca,

If you build the dictionary using stemmed (or lemmatized) terms, and you
pass your input document also through the same transformation, then you can
do fuzzier matching than exact match.
