Thanks Ryan. I now know the reason why.
Before I explain the reason, let me correct the mistake I made in my earlier
mail. I was not using the first document mentioned in the xml . Instead it
was this one:
<doc>
<field name="id">IW-02</field>
<field name="name">iPod & iPod Mini USB 2.0 Cable</field>
<field name="manu">Belkin</field>
<field name="cat">electronics</field>
<field name="cat">connector</field>
<field name="features">car power adapter for iPod, white</field>
<field name="weight">2</field>
<field name="price">11.50</field>
<field name="popularity">1</field>
<field name="inStock">false</field>
</doc>
The reason I was getting strange result was because of the character "i".
Here is what I learnt from debug info:
"debug":{
"rawquerystring":"id:neardup06",
"querystring":"id:neardup06",
"parsedquery":"features:og features:en features:til features:er
features:af features:der features:ts features:se features:i features:p
features:pet features:brag features:efter features:zombier features:k
features:tilbag features:ala features:sviner features:folk
features:klassisk features:resid features:horder features:lidt
features:man features:denn",
"parsedquery_toString":"features:og features:en features:til
features:er features:af features:der features:ts features:se
features:i features:p features:pet features:brag features:efter
features:zombier features:k features:tilbag features:ala
features:sviner features:folk features:klassisk features:resid
features:horder features:lidt features:man features:denn",
"explain":{
"id=IW-02,internal_docid=8":"\n0.0050230525 = (MATCH) product of:\n
0.12557632 = (MATCH) sum of:\n 0.12557632 = (MATCH)
weight(features:i in 8), product of:\n 0.17474915 =
queryWeight(features:i), product of:\n 1.9162908 =
idf(docFreq=3)\n 0.09119135 = queryNorm\n 0.71860904 =
(MATCH) fieldWeight(features:i in 8), product of:\n 1.0 =
tf(termFreq(features:i)=1)\n 1.9162908 = idf(docFreq=3)\n
0.375 = fieldNorm(field=features, doc=8)\n 0.04 = coord(1/25)\n"}}}
The field "features" uses the default fieldtype - "text" in the schema.xml.
The problem was solved by adding the character "i" to the
stopwords.txtfile. the "i"s in document 2 were matched with the "i" in
"iPod" of document
1.
I still have to figure out why a single character - "i" - matched the "i" in
a word - "iPod".
