# Simple

This is the HPE recommended `Combine` option.

When IDOL Server indexes very long texts, by default it breaks them into sections, and indexes them as individual documents. Each document has its own ID, but they all have the same document reference. This process stabilizes indexing and ensures that the most relevant section of a text returns when you query IDOL Server (for example, rather than an entire book). However, if several sections match the query, each section returns as a result. A query can contain multiple results with the same document reference, which belong to the same text, for example, different pages of the same book. If you display each result with the `Print` action parameter set to `AllSections`, you see the same text every time.

You can prevent IDOL Server from returning different sections of the same source text by adding `Combine=Simple` to the query. IDOL Server displays only the section that has the highest conceptual similarity to the query (unless you add `Print=AllSections` to the query, in which case it displays the entire source text). If multiple sections have the same conceptual relevance, IDOL Server returns the one with the lowest section number.

For example:

    http://IDOLhost:port/action=Query&Text=The Moonstone&Combine=Simple

In this example, if several results derive from the same source text, IDOL Server displays only the result that has the highest relevance to the query text.
