Index search

The local search machine can be used to query project data that has been transformed to XML and indexed. An overview of the currently stored data sets is given below. The search engine is based on Solr and Lucene technology.

Query syntax

Query type Example Comments
One keyword query "Lipoprotein",   "E2F6" records that contain the word 'Lipoprotein' / 'E2F6'
Negative query (exclusion) "-Lipoprotein" records that do not contain 'Lipoprotein'
Field query "vindex:biomodels",   "identifier:OCT4" Searches specific fields, e.g. vindex (=subindex), or identifier
Boolean combinations: OR, AND (default). AND can be omitted "(oct4 OR klf) AND sox2 AND -vindex:uniprot" records containing OCT4 or KLF together with SOX2, but without Uniprot results
Wild card query (one character) "te?t" records that contain 'test', 'tent', 'text', etc.
Wild card query (multiple characters) "te*t" records that contain 'test', 'tent', 'text', 'termite', 'temperature' etc.
Fuzzy search "proteome~" records that contain terms like protein, proteomics, proteasome, etc.
Range query "field:[0 TO 0.05]",  "vindex:[a* TO z*]" records with values within certain ranges, e.g.
p-values < 0.05 or words starting with certain characters
