  1. POHelp understanding Solr debug
    text
    copied!<p>I'm debugging my boosting algorithm and I can't make ends-up of the debug text. In question is the following text:</p> <blockquote> <p>358.5638 = product(const(1.0E10),div(int(ViewCount)=47092,ms(const(1313350611991),str(UploadDate)=2008-09-19T16:30:16Z)))</p> </blockquote> <p>Now, if I do my math correctly we get 1e10*47092/ms(NOW,''that_date'')=1e10*47092/9.1510096E10 = 5146.09885.</p> <p>What's worse is that there doesn't seem to be a pattern to it. In the debug information for the result proceeding this example, solr calculates 314.40195 whereas I calculate 33667.1973. So from my perspective, solr's getting these two results backwards!</p> <p>Were am I getting confused? </p> <p>For the interested reader: here's the debug info for both of the above examples. However I am only interested in the small FunctionQuery portions at the bottom of each entry.</p> <pre><code>&lt;str name="10525"&gt; 45.199703 = (MATCH) sum of: 1.2967482 = (MATCH) max plus 0.1 times others of: 0.1823791 = (MATCH) weight(primary_text_phonetic:FRT^0.25 in 6498), product of: 0.14184701 = queryWeight(primary_text_phonetic:FRT^0.25), product of: 0.25 = boost 4.7508817 = idf(docFreq=4940, maxDocs=210282) 0.11942795 = queryNorm 1.285745 = (MATCH) fieldWeight(primary_text_phonetic:FRT in 6498), product of: 1.7320508 = tf(termFreq(primary_text_phonetic:FRT)=3) 4.7508817 = idf(docFreq=4940, maxDocs=210282) 0.15625 = fieldNorm(field=primary_text_phonetic, doc=6498) 1.2785102 = (MATCH) weight(primary_text:friday in 6498), product of: 0.6856842 = queryWeight(primary_text:friday), product of: 5.741405 = idf(docFreq=1834, maxDocs=210282) 0.11942795 = queryNorm 1.8645759 = (MATCH) fieldWeight(primary_text:friday in 6498), product of: 1.7320508 = tf(termFreq(primary_text:friday)=3) 5.741405 = idf(docFreq=1834, maxDocs=210282) 0.1875 = fieldNorm(field=primary_text, doc=6498) 1.0804138 = (MATCH) max plus 0.1 times others of: 0.18776983 = (MATCH) weight(phrase_phonetic:FRT^0.25 in 6498), product of: 0.14540447 = queryWeight(phrase_phonetic:FRT^0.25), product of: 0.25 = boost 4.870032 = idf(docFreq=4385, maxDocs=210282) 0.11942795 = queryNorm 1.2913622 = (MATCH) fieldWeight(phrase_phonetic:FRT in 6498), product of: 1.4142135 = tf(termFreq(phrase_phonetic:FRT)=2) 4.870032 = idf(docFreq=4385, maxDocs=210282) 0.1875 = fieldNorm(field=phrase_phonetic, doc=6498) 1.0616368 = (MATCH) weight(phrase:friday in 6498), product of: 0.6914851 = queryWeight(phrase:friday), product of: 5.789977 = idf(docFreq=1747, maxDocs=210282) 0.11942795 = queryNorm 1.5352995 = (MATCH) fieldWeight(phrase:friday in 6498), product of: 1.4142135 = tf(termFreq(phrase:friday)=2) 5.789977 = idf(docFreq=1747, maxDocs=210282) 0.1875 = fieldNorm(field=phrase, doc=6498) 42.82254 = (MATCH) FunctionQuery(product(const(1.0E10),div(int(ViewCount),ms(const(1313350611991),str(UploadDate))))), product of: 358.5638 = product(const(1.0E10),div(int(ViewCount)=47092,ms(const(1313350611991),str(UploadDate)=2008-09-19T16:30:16Z))) 1.0 = boost 0.11942795 = queryNorm &lt;/str&gt;&lt;str name="190925"&gt; 41.04527 = (MATCH) sum of: 1.6962012 = (MATCH) max plus 0.1 times others of: 0.28546843 = (MATCH) weight(primary_text_phonetic:FRT^0.25 in 4562), product of: 0.14184701 = queryWeight(primary_text_phonetic:FRT^0.25), product of: 0.25 = boost 4.7508817 = idf(docFreq=4940, maxDocs=210282) 0.11942795 = queryNorm 2.0125093 = (MATCH) fieldWeight(primary_text_phonetic:FRT in 4562), product of: 3.8729835 = tf(termFreq(primary_text_phonetic:FRT)=15) 4.7508817 = idf(docFreq=4940, maxDocs=210282) 0.109375 = fieldNorm(field=primary_text_phonetic, doc=4562) 1.6676544 = (MATCH) weight(primary_text:friday in 4562), product of: 0.6856842 = queryWeight(primary_text:friday), product of: 5.741405 = idf(docFreq=1834, maxDocs=210282) 0.11942795 = queryNorm 2.4321027 = (MATCH) fieldWeight(primary_text:friday in 4562), product of: 3.8729835 = tf(termFreq(primary_text:friday)=15) 5.741405 = idf(docFreq=1834, maxDocs=210282) 0.109375 = fieldNorm(field=primary_text, doc=4562) 1.8006895 = (MATCH) max plus 0.1 times others of: 0.31294972 = (MATCH) weight(phrase_phonetic:FRT^0.25 in 4562), product of: 0.14540447 = queryWeight(phrase_phonetic:FRT^0.25), product of: 0.25 = boost 4.870032 = idf(docFreq=4385, maxDocs=210282) 0.11942795 = queryNorm 2.1522703 = (MATCH) fieldWeight(phrase_phonetic:FRT in 4562), product of: 1.4142135 = tf(termFreq(phrase_phonetic:FRT)=2) 4.870032 = idf(docFreq=4385, maxDocs=210282) 0.3125 = fieldNorm(field=phrase_phonetic, doc=4562) 1.7693945 = (MATCH) weight(phrase:friday in 4562), product of: 0.6914851 = queryWeight(phrase:friday), product of: 5.789977 = idf(docFreq=1747, maxDocs=210282) 0.11942795 = queryNorm 2.5588324 = (MATCH) fieldWeight(phrase:friday in 4562), product of: 1.4142135 = tf(termFreq(phrase:friday)=2) 5.789977 = idf(docFreq=1747, maxDocs=210282) 0.3125 = fieldNorm(field=phrase, doc=4562) 37.548378 = (MATCH) FunctionQuery(product(const(1.0E10),div(int(ViewCount),ms(const(1313350611991),str(UploadDate))))), product of: 314.40195 = product(const(1.0E10),div(int(ViewCount)=41292,ms(const(1313350611991),str(UploadDate)=2011-03-25T21:03:52Z))) 1.0 = boost 0.11942795 = queryNorm &lt;/str&gt; </code></pre>
