Indexing images for use in a searchable index includes receiving an image. A joint histogram may be computed for the received image such that the joint histogram includes joint features. A searchable index based on the joint features within the joint histogram may be created using an index methodology. Text also may be received and a searchable index of the received text may be created. A weighting factor may be applied to at least one of the joint features within the joint histogram such that the joint histogram represents a weighted joint histogram. A searchable index may include a first joint histogram feature corresponding to at least a first image, which includes the first joint histogram feature. The searchable index also may include a second joint histogram feature corresponding to at least a second image, which includes the second joint histogram feature.
