Hi
I use a sample embedded Apache Solr to create a Lucene index with few documents
for tests purpose.
Documents have text string, sint, sfloat, bool, and date fields, each of them
are indexed.
At this time they are also stored but only the ids documents will be stored at
the end.
I want to list the terms of index. I don't found a way this solr api so I made
a try Apache Luke ( Lucene api.)
Here the code of luke to see terms of index :
public void terms(String field) throws CorruptIndexException, IOException {
validateIndexSet();
validateOperationPossible();
SortedMap<String,Integer> termMap = new TreeMap<String,Integer>();
IndexReader reader = null;
try {
reader = IndexReader.open(indexName);
TermEnum terms = reader.terms(); // return an enumeration of terms
while (terms.next()) {
Term term = terms.term();
if ((field.trim().length() == 0) || field.equals(term.field())) {
termMap.put(term.field() + ":" + term.text(),
new Integer((terms.docFreq())));
}
}
int nkeys = 0;
for (String key : termMap.keySet()) {
Lucli.message(key + ": " + termMap.get(key));
nkeys++;
if (nkeys > Lucli.MAX_TERMS) {
break;
}
}
} finally {
closeReader(reader);
}
}
But for sfloat field (is the same for sint) I don't see the value of the term.
The class Term of Lucene have just 2 fields of type String (name and value)
Here values returned for the dynamic field f_float of type sfloat :
f_float:┼??
f_float:┼??
f_float:┼?l
f_float:┼??
f_float:┼??
So,
have a way to convert term in the good type (int, date, float ) ?
Or Have a way to see index terms with solr api ?
Thanks for help
