Can morelikethis expose the node nid?

This is a feature that most definitely should be added. Look for it in the next alpha release.

Thanks,
Chris

Hi scotjam,

After having some time to read through my own code and think about this a little more, you can actually just call the luceneapi_morelikethis_nid_get() function to obtain the node ID. It statically caches the node ID that it calculates, so only one query is executed no matter how many times you call it. I think that it makes the most sense to make use this function as opposed to passing a node ID to the theme function, but I am willing to discuss. My thinking is that there might be cases in the future when non-node text is used as the source when calculating a moreLikeThis query, so a node ID might not always be available.

Either way, thanks for pointing out this use case and making me think more about it,
Chris

Please disregard the last post, as I misunderstood what you meant. The item (in this case the node), should most definitely be available for the matched items. Obviously I was thinking about the node being used as the source text. Changing back to a task to make this information available.

A solution has been committed at #264652. The entire hit object is attached to each item in $itmes, so you will be able to get the node ID. Code example is below:

/**
 * Implementation of theme_luceneapi_morelikethis_item().
 *
 * $item now has the 'hit' key in addition to 'title' and 'link'.
 */
function mytheme_luceneapi_morelikethis_item($item) {
  $output = '';

  // get the node ID for the matched item
  $nid = $item['hit']->nid;

  // do whetever you need to do to format the return value
  // ...
  // ...
  return $output;
}
