Node search should be ordered by relevancy score, not creation date

[fmteixeira]

When searching in the mesh-ui, the results are ordered by the creation date instead of the relevancy score, this creates the following problems:

• The most relevant nodes are not at the top of the search result list (example displayed on the image below)
• When there's more than 10 results found, only the first 10 are shown as there's no pagination
• The lack of pagination and ordering by creation date opens the possibility to bury the most relevant nodes on inaccessible pages

It seems that this is affected by the code on the images below, I suggest removing the "sort" parameters from these queries as it will use the relevancy by default.
