We report results on the first matched-filtering search for binaries withcompact objects having large tidal deformabilities in the LIGO-Virgogravitational wave (GW) data. The tidal deformability of a body is quantifiedby the ``Love number" $\Lambda \propto \hskip 1pt (r/m)^5$, where $r/m$ is thebody's (inverse) compactness. Due to its strong dependence on compactness, the$\Lambda$ of larger-sized compact objects can easily be many orders ofmagnitude greater than those of black holes and neutron stars, leaving phaseshifts which are sufficiently large for these binaries to be missed by binaryblack hole (BBH) templated searches. In this paper, we conduct a search usinginspiral-only waveforms with zero spins but finite tides, with the search spacecovering chirp masses $3 M_\odot < \mathcal{M} < 15 M_\odot$ and effectivetidal deformabilities $10^2 \lesssim \tilde{\Lambda} \lesssim 10^6$. We find nostatistically significant GW candidates. This null detection implies an upperlimit on the merger rate of such binaries in the range $[1-300] \hskip 2pt\text{Gpc}^{-3} \text{year}^{-1}$, depending on $\mathcal{M}$ and$\tilde{\Lambda}$. While our constraints are model agnostic, we discuss theimplications on beyond the Standard Model scenarios that give rise to bosonstars and superradiant clouds. Using inspiral-only waveforms we recover many ofthe BBH signals which were previously identified with fullinspiral-merger-ringdown templates. We also constrain the Love number of blackholes to $\Lambda \lesssim 10^3$ at the 90\% credible interval. Our work is thefirst-ever dedicated template-based search for compact objects that are notonly black holes and neutron stars. Additionally, our work demonstrates a novelway of finding new physics in GW data, widening the scope of potentialdiscovery to previously unexplored parameter space.
